After 3 or so hours ubuntu 16.04 finally installed & what lovely surprise,no launcher a big black cross instead of mouse cursor & slower than a bowl of soup warming up in the freezer, can someone please advise me how to get this running properly. Many thanks.

  Shut down the company and stop releasing new versions, obviously.
  - chillingeffect 10y ago
    Yeah, it's really a shame. I thought the open source movement had a lot going for it, but they should have thought this part out better. It's okay though, I honestly feel we can take most of what we learned and apply it to the Commodore 64, which, while closed source, most "black hat" hackers can patch the kernel of to include execution of the Binaries Formerly Known As Ubuntu. The process will be different, though: After powering on the system and reaching the READY string signaling the BASIC interpreter, you'll POKE the unicode name-string of the package you want to update to the user space at $C000, then execute an SYS command to set the CPU's program counter to the vector of the package installation.

I love the part about simplifying packaging via 'snap'. Now, I would love to know, if I'm a maintainer of Foo (and you can get it today via `apt-get install foo`), how will I be able to start packaging using snap rather than relying on deb packages that come from debian? I'd love any feedback, cheers!
- koolba 10y ago
  What is snap? I can't find mention of it anywhere on the release notes page.
  - anuragsoni 10y ago
    https://developer.ubuntu.com/en/desktop/ https://developer.ubuntu.com/en/desktop/ https://developer.ubuntu.com/en/snappy/build-apps/ https://developer.ubuntu.com/en/snappy/build-apps/ The ubuntu developer page has a good description of snaps and how to create them. In short its a package that contains all its dependencies.
- tomswartz07 10y ago
  Just a side note, as well: `apt-get` is depreciated, they've moved to just plain `apt` `apt install foo`
  - nailer 10y ago
    Nice. There were a couple of things that were 'apt-cache', I could never remember which, I gather 'apt' does those too?
    - tomku 10y ago
      It does 'seach' and 'show' from apt-cache at least, not sure about any others.
      - __david__ 10y ago
        Oddly apt's `search` output is terrible compared to apt-cache's. If they want me to switch to the new command they should at least make it the same or better, not a couple steps backward.
xd1936 10y ago
Does anybody know what packages are going to be bundled as Snaps, and what packages will still be debs? Firefox? Libreoffice?

I've been on 16.04 for a few days now, and while I did have to work through some bugs (such as sddm and lightdm fighting each other) I've been impressed so far with the improvements. Inused to hate on Ubuntu, but on my 2014 Macbook Pro, it was the one distro that "just worked", and since I mostly run debian servers, I figure Sticking to the similar ecosystem reduces mental load of switching. I still have my issues with Shuttleworth and Canonical, but hey, it's linux, so I can remove the crap I dont like (unlike some things, staring at you windows 10).
- themodelplumber 10y ago
  Curious what you want to remove in Windows 10. Not an evangelist, just set it up on a dual-boot refurb for a friend and thought the initial experience wasn't bad.

nailer 10y ago
For anyone packaging software on Linux, this now means every major distro - Debian, RHEL/CentOS, Arch and now Ubuntu - supports .service files. No need for bash scripts, custom watchdog and daemonise tools, etc.
- atonse 10y ago
  This is pretty much the only reason I've been waiting for 16.04 – to get rid of upstart scripts and standardize on systemd. Still going to wait for a couple months while people iron out initial bugs but definitely excited about this release.
  - listic 10y ago
    > to wait for a couple months while people iron out initial bugs There's going to be a 16.04.1 release just 3 months away from the initial LTS release; I believe it is just for that. https://wiki.ubuntu.com/TrustyTahr/ReleaseSchedule https://wiki.ubuntu.com/TrustyTahr/ReleaseSchedule - this schedule is for 14.04, but I believe it's been the same for quite a few years already.
    - atonse 10y ago
      Great, thanks. I will probably install this on internal servers (non-production, non-critical, CI, etc) first because I'm also impatient. :)
- soccerdave 10y ago
  I wonder how big the installation of Amazon Linux is? They are still not on systemd. Also, CentOS 6 still has support for 4 more years so probably can't throw away all the bash yet.
  - falcolas 10y ago
    Very good points. Amazon linux is pretty popular within AWS, and LTS CentOS and RHEL have huge install bases for larger corporate environments. For that matter, Ubuntu 14.04 is still supported for another two years, and that's still upstart.
creshal 10y ago
Small warning: Ubuntu's "do you want to upgrade" popup window defaults to "yes". Had to find that out the hard way when a user hit Enter the wrong moment and was suddenly sitting in front of a bricked system.
- bad_user 10y ago
  Usually you press Enter to accept things and ESC to cancel. Also, it first downloads all packages before upgrading, so you should've had time to cancel it.
- amelius 10y ago
  Is upgrade failing in general or in this specific case only?
  - creshal 10y ago
    I've no idea. `apt install -f` fixed everything and I didn't bother probing into it further. (We only have Ubuntu on two machines, everything else is Arch or Debian.)
    - bsharitt 10y ago
      I had a similar experience upgrading my laptop(though I initiated the upgrade on purpose). Just crapped out, but an apt install -f followed by a dist-upgrade fixed it all and it seems to have worked.

>Support for scaling cursors in HiDPI environments So 4k resolution support is becoming recognized here?
- themodelplumber 10y ago
  This reminds me, I'd really like to know what to expect with a 4K monitor in 16.04.
  - patwolf 10y ago
    I've been running 16.04 beta for the past month on a Thinkpad P70 with a 4k display, and scaling has been great. The OS UI elements (like menu bars) can be scaled to any size. Most applications seem to work out of the box. The ones that have given me the most problems are a handful of desktop apps implemented in an embedded browser (like Spotify) where I have to set an extra command flag to properly scale.
    - themodelplumber 10y ago
      That's great to hear, thanks. I'm using Xubuntu most of the time but I'll probably give it a shot and upgrade myself.

Been using 16.04 on my XPS 13 for a week or so now, it finally supports nearly everything (bluetooth is a couple of extra commands) out of the box, and I've not had any issues so far.
- criddell 10y ago
  Are you happy with battery life? For laptops, I've always stuck with Apple machines but in my experience even Windows uses less power than Linux.
  - smhg 10y ago
    I've been using an XPS 13 for 8 months as my main development machine and battery life hasn't been an issue. I regularly go out for a (e.g. coffee shop) working day and I don't have to charge. There were some issues with earlier Ubuntu/Linux/BIOS versions, but most have disappeared with new releases. The last one is a palm detection issue with the touchpad, but it should to be fixed in 16.04. And if you can't wait, at least you can fix things yourself if you want.

      > The last one is a palm detection issue with the touchpad, but it should to be fixed in 16.04. And if you can't wait, at least you can fix things yourself if you want. I'm not sure if I could fix palm detection. I am certain that I could spend a lot of time trying to fix it and for me, that time would probably be better spent elsewhere.

      Are you using the sputnik "developer edition" or the standard retail version of the XPS 13?
      - smhg 10y ago
        The Sputnik version. That indeed reminds me I swapped the wifi card for an Intel one. Because they are better supported and it was cheap. The original one was definitely working though.
gravypod 10y ago
So when will I be able to `sudo do-release-upgrade`? Does not seem to be working on my end. I'm using Xubuntu.
- abrowne 10y ago
  Are you on 15.10 or 14.04 LTS? For the latter, I think not until 16.04.1 is released. Otherwise, probably soon.
  - gravypod 10y ago
    I'm on xubuntu 15.10.
    - abrowne 10y ago
      You can always do `sudo do-release-upgrade -d` (for development version), but it should work in the next 24 hours.
- edwinksl 10y ago
  It has not been officially released yet, so `sudo do-release-upgrade` still fails.
ivank 10y ago
Notes from my 15.10 -> 16.04 upgrade: 1) If you use the nvidia drivers from the graphics-drivers PPA, starting the default non-root X server will hang with no graphics output. Installing xserver-xorg-legacy fixes this. 2) LXC+Linux 4.4 seems to be very broken: https://github.com/lxc/lxd/issues/1666#issuecomment-212903111 https://github.com/lxc/lxd/issues/1666#issuecomment-21290311... 3) Pulseaudio now uses shared memory and playing audio inside a firejail will break the pulseaudio server: https://github.com/netblue30/firejail/issues/69#issuecomment-212694241 https://github.com/netblue30/firejail/issues/69#issuecomment...
- cyphar 10y ago
  Yeah, we've seen similar issues with runC on point 2. I don't think it's an upstream kernel issue as it didn't happen on openSUSE Tumbleweed when we had 4.4 (we're on 4.5 now). So presumably it's some patch Ubuntu applies.
- josteink 10y ago
  > LXC+Linux 4.4 seems to be very broken Seeing as my main use for my current 14.04 install is LXC containers, I think I will hold off a little then. Thanks for the warning :)
- Pengwin 10y ago
  no new ubuntu release would be complete without graphics issues from Nvidia and AMD. I say AMD too because FGLRX is out of 16.04. After all the Issues i had with intel/amd/nvidia stiwching gpus in the ivy bridge days i just gave up buying nvidia and AMD, and boy has it made linux easier.

Is an update from 14.04 painless or would you recommend reinstalling? I'd like some newer packages but don't really feel like setting up the whole system again with a reinstall.
- maaarghk 10y ago
  Pretty painless - I've just ran this on two servers (not in production): sudo do-release-upgrade or if you're on a server sudo do-release-upgrade -d although they don't recommend doing that on a production server because the .1 release usually has a lot of bugfixes. It took about half an hour followed by a reboot. Occasionally had to intervene to tell it to overwrite config files I hadn't touched or to let me do a merge if I had. Obviously make sure you have backups first.
- majewsky 10y ago
  If you don't feel a particular urge to upgrade right now, it's probably not a bad idea to wait for the first service pack (16.04.1), which usually comes a few months later. Most kinks should be ironed out by then.
- Rezo 10y ago
  Per the release notes [0], upgrades from 14.04 aren't enabled. They will be enabled with the 16.04.1 LTS release, in 3 months time. [0] https://wiki.ubuntu.com/XenialXerus/ReleaseNotes https://wiki.ubuntu.com/XenialXerus/ReleaseNotes
- pkaye 10y ago
  I always wait a month before upgrading/reinstalling. I have done upgrades in the past through multiple versions and they generally go smoothly but there might a minor glitch or two that requires manual intervention to fix (usually solved though search google for advice.) Another thing I've done is keep /home on a separate partition so I can nuke everything else for a clean install if needed. In such cases, I backup the /etc directory beforehand to recover configuration details as needed.

- hansjorg 10y ago
  What is the significance of this? Doesn't Canonical already update the package (lagging a day or two behind the official release) for the lifetime of the Ubuntu version?
  - takno 10y ago
    I'd guess that Firefox is a fairly good candidate for this kind of packaging just because it has relatively few external dependencies, and lots of Mozilla-specific dependencies which are rarely used by other software
  - rawfan 10y ago
    Firefox is going to be used as a testbed for snap packages.
  - stubish 10y ago
    It will be Firefox, in a sandbox, out of the box.
- symtos 10y ago
  Using binaries provided by Mozilla is not a good idea (unless they do things differently with the snaps). They are not hardened in any way; ie. no PIE (rendering ASLR pretty much useless), no stack canaries, no relro, ..., making it a lot easier to exploit any given sec-related bug. $ hardening-check ./firefox ./firefox: Position Independent Executable: no, normal executable! Stack protected: no, not found! Fortify Source functions: no, only unprotected functions found! Read-only relocations: no, not found! Immediate binding: no, not found! Absolutely ridiculous given the amount of vulns likely to linger in its codebase. It should also be noted that Firefox is one of the few packages that Canonical keeps aligned with Mozilla releases (even 12.04 LTS has the latest firefox), and: $ hardening-check /usr/lib/firefox/firefox /usr/lib/firefox/firefox: Position Independent Executable: yes Stack protected: yes Fortify Source functions: yes (some protected functions found) Read-only relocations: yes Immediate binding: yes

Valid states are 'starting, running'. The machine is in the 'gurumeditation' state. Please verify everything is configured properly and try again. If the provider you're using has a GUI that comes with it, it is often helpful to open that and watch the machine, since the GUI often has more helpful error messages than Vagrant can retrieve. For example, if you're using VirtualBox, run `vagrant up` while the VirtualBox GUI is open. The primary issue for this error is that the provider you're using is not properly configured. This is very rarely a Vagrant issue.
- matt4077 10y ago
  Someone else in this thread posted something rather nonsensical about switching to Commodore 64. I was just about to make a guru meditation joke when I saw that someone apparently beat me to it. I'm running 16.04 with the Vagrant/Virtualbox image from atlas. I've tried getting it to work in the google cloud but had no luck there so far (it's possibly just the ssh key injection that failed, haven't had time to investigate).

michaelmior 10y ago
For anyone like myself who isn't a big fan of the Unity interface, check out Ubuntu MATE[0]. The MATE desktop environment is very similar to pre-Unity Ubuntu. It seems like the final 16.04 release hasn't landed yet but I'm sure it will later today. Ubuntu MATE is also one of the derivative distros that has been granted LTS status by Canonical. [0] https://ubuntu-mate.org/ https://ubuntu-mate.org/
- edent 10y ago
  I'll second that. Mate is amazing. I can also recommend Cinnamon.
  - noir_lord 10y ago
    Both are great, Xubuntu is excellent and still my goto since it has pretty much exactly the features I want from a DE. It's nice to have good choices that use the old paradigms. XFCE 4.12 pretty much feels exactly like Gnome 2 towards the end.
  - teekert 10y ago
    Ubuntu Mate is also great on the Raspberry Pi. all the GPIO stuff just works as in Raspbian but you get a more modern desktop (using the classical gnome2 layout) and Ubuntu as the base (which to mee means easier setup of things like a mail server.) I'm hoping Owncloud starts to use Snaps.
  - satysin 10y ago
    I would love to see an "official" Cinnamon build in the way we have Xubuntu, etc.

> Online searches in the dash are now disabled by default [1] A welcome and saner default.

  Besides the default online dash searches pre-Xenial, do you mind sharing what other changes are allowing you to consider moving back?
- zanny 10y ago
  As someone who has used Arch for 4 years, the bleeding edge got boring. I haven't had a major breakage in at least a year, probably longer, unless you count KDE 4 -> 5 being a breakage - one any 14.04 to 16.04 upgrader will also have to contend with. The last major show stopper I can recall was when Arch dropped security hooks from the kernel and I had to get rid of my MAC.
- takno 10y ago
  I never moved to mint, but I did recommend trying it to some people who really didn't like unity. I pretty much stopped doing that when they had the security issues last year. Is that what is prompting you to look at switching back, or are you just more reconciled to unity in general now?

    If one wants Ubuntu and GNOME, there's https://ubuntugnome.org/ https://ubuntugnome.org/
  - noisy_boy 10y ago
    That is one and I read online (can't find the source now) that Mint development doesn't respect compatibility/play well with other open source developers. I don't know how much of it is true but for me, compatibility is important. For almost 5-6 years, I have never formatted my home directory. So if my distribution is, for example, creating config in a non-compatible fashion, I won't be able to move to another distro. I know that typically distros don't modify individual program's dotfile/config etc but I guess I'm a bit paranoid about it.

csense 10y ago
They should just stop publishing MD5SUMS for new releases. By now, everybody should have gotten the word that MD5 has been broken. The security of the MD5 has been severely compromised, with its weaknesses having been exploited in the field, most infamously by the Flame malware in 2012. The CMU Software Engineering Institute considers MD5 essentially "cryptographically broken and unsuitable for further use". [1] [1] https://en.wikipedia.org/wiki/MD5 https://en.wikipedia.org/wiki/MD5
- pritambaral 10y ago
  They do provide SHA256SUMS. I guess MD5SUMS are there for legacy purposes. It is on users to stop using MD5SUMS and move to SHA256SUMS

  I've always wondered this but felt too embarrassed to ask, screw it. Let's say the ubuntu 16 iso is infected with some kind of malware by a 3rd party. If they have control of the file, would they not have control of the checksum displayed on the site? I can understand if the checksum is spread to other sites for cross-reference but I'm having trouble seeing why a checksum from the same location as the file you're downloading is worth anything. Any insight?
  - defective 10y ago
    It's worth it for error-checking.
  - eloisant 10y ago
    If they infect at the source, yes. But if just one mirror is infected, or one of the CDN servers, the attacker may not be able to change the checksum on the official site.
    - thieving_magpie 10y ago
      Ah - that makes sense. I knew their had to be an easy answer but I couldn't see it. Thanks

PSA: If you're running a HTTP/2 server like NGINX on the 14.04 LTS you'll want to upgrade to this release. Google Chrome will no longer support HTTP/2 on vanilla 14.04 after May 15th [0], even if you're using the latest official upstream NGINX packages. This is because 14.04 ships with a version of OpenSSL that does not support the ALPN extension (prior to OpenSSL 1.0.2 you're limited to NPN, now deprecated). There was a bit of back-and-forth about the exact date, as the change was originally scheduled for earlier. However, Chrome decided to specifically push back the date so that there would be an Ubuntu LTS release available with the required support [1]. If you're still stuck on SPDY, that's going to be dropped too, so there's really no good reason not to simply use HTTP/2 at this point.

  If you use 14.04, you usually upgrade at the first point release to 16.04.01, not now at 16.04.00. Only 15.10 will immediately suggest an update. Is this outdated or not applicable to servers?
  - Rezo 10y ago
    That is correct, upgrades are not enabled between LTS releases at this time, also for servers AFAIK. Either way, personally I would never upgrade a server in place these days. Treat your servers like cattle not pets: Rebuild from new base image, validate, put into LB/proxy, terminate old stack.
    - poooogles 10y ago
      This. Our upgrade path was changing a variable in our packer config. Literally the easiest upgrade ever.
  - collinmanderson 10y ago
    You should hold off doing in-place upgrades using "do-release-upgrade" until 16.04.1 (due August/September). However, you can also "upgrade" your stack by building a new image using 16.04 from scratch, and that doesn't need to wait until 16.04.1.

From some sources, I've heard that it appears that those with AMD graphics will suffer a downgrade in performance until the point release in June. I think by June, the open source AMD drivers should be up to speed or have the same features as the previous flgrx ones. From what I gather it's more like a downgrade in supported features. I think this is just an issue if you are doing 3D graphics work or gaming.
- deleted 10y ago
  [deleted]
- fulafel 10y ago
  Most people with AMD graphics have been using the open source drivers and will just see all around improvements. edit: Also, you can get Vulkan with the new drivers.
  - rleigh 10y ago
    This very much depends upon whether you want the latest OpenGL 4.x features or not. Compute shaders, etc. Most people won't notice, but if you want to develop or use applications using these features, the open drivers aren't yet up to par, so for these cases it is indeed a major downgrade.
    - chippy 10y ago
      So to be more accurate, its more developing with these graphics functions, rather than gaming? games developing vs games playing.
    - tormeh 10y ago
      Only temporarily. The closed source ones are legacy now, afaik. I believe AMD has said they want to only use open source drivers with closed source plugins; i.e. hybrid drivers. Anyone know if it's going to be the same on Windows? Open source with proprietary plugins?

If I have a software RAID that I created under MINT using `mdadm`. will the partition work the same after installing Ubuntu 16.04 or will I have to re-synch the volumes?
- e12e 10y ago
  AFAIK mdadm has been stable for years (one of the reasons why I prefer software raid to hardware raid). As long as you boot into anything resembling a recent Linux kernel along with a userspace with mdadm support, you should be fine. If in doubt, boot from a live-cd/usb and see if you can mount your drives ok.

I gotta say, Canonical/Ubuntu has a lot of respect in my book for how dependable the distro has been over the years. I've been through my fair share of distros, and one of my employees goes through a new Linux install at least once a week. Ubuntu is one of the few distros that almost always works. Other distros will have one problem or another with this machine or that, but put Ubuntu on there and everything is fine (well, as fine as Linux gets). A few weeks ago I had to dig up an old 12.04 machine and bring it back to the modern age. Much to my surprise, I was able to upgrade it all the way to 15.10 with minimal hassle. While the normal apt repos were dead for 12.04, Canonical keeps around an archived mirror. So you just edit the sources file to point at the archive, and then you can upgrade from there. Impressive. Not that Canonical/Ubuntu don't have their warts. The Amazon fiasco, Unity, their cloud services, etc. And at the end of the day it's still Linux, with all the problems that brings. But, all things considered, I rate Ubuntu as the best of the bunch and feel grateful for the gift they give to the community.
- paulddraper 10y ago
  Yeah, take Ubuntu and their repos, throw out Unity, find a way to get a Java release from the last few years, do the graphics drivers dance, and you have a very solid, reasonably compatible development environment.

  Yeah, it's really a shame. I thought the open source movement had a lot going for it, but they should have thought this part out better. It's okay though, I honestly feel we can take most of what we learned and apply it to the Commodore 64, which, while closed source, most "black hat" hackers can patch the kernel of to include execution of the Binaries Formerly Known As Ubuntu. The process will be different, though: After powering on the system and reaching the READY string signaling the BASIC interpreter, you'll POKE the unicode name-string of the package you want to update to the user space at $C000, then execute an SYS command to set the CPU's program counter to the vector of the package installation.

I love the part about simplifying packaging via 'snap'.

I'd love any feedback, cheers!

I've been on 16.04 for a few days now, and while I did have to work through some bugs (such as sddm and lightdm fighting each other) I've been impressed so far with the improvements. Inused to hate on Ubuntu, but on my 2014 Macbook Pro, it was the one distro that "just worked", and since I mostly run debian servers, I figure Sticking to the similar ecosystem reduces mental load of switching. I still have my issues with Shuttleworth and Canonical, but hey, it's linux, so I can remove the crap I dont like (unlike some things, staring at you windows 10).

For anyone packaging software on Linux, this now means every major distro - Debian, RHEL/CentOS, Arch and now Ubuntu - supports .service files. No need for bash scripts, custom watchdog and daemonise tools, etc.

atonse 10y ago
This is pretty much the only reason I've been waiting for 16.04 – to get rid of upstart scripts and standardize on systemd. Still going to wait for a couple months while people iron out initial bugs but definitely excited about this release.
- listic 10y ago
  > to wait for a couple months while people iron out initial bugs There's going to be a 16.04.1 release just 3 months away from the initial LTS release; I believe it is just for that. https://wiki.ubuntu.com/TrustyTahr/ReleaseSchedule https://wiki.ubuntu.com/TrustyTahr/ReleaseSchedule - this schedule is for 14.04, but I believe it's been the same for quite a few years already.

    Great, thanks. I will probably install this on internal servers (non-production, non-critical, CI, etc) first because I'm also impatient. :)

I wonder how big the installation of Amazon Linux is? They are still not on systemd. Also, CentOS 6 still has support for 4 more years so probably can't throw away all the bash yet.
- falcolas 10y ago
  Very good points. Amazon linux is pretty popular within AWS, and LTS CentOS and RHEL have huge install bases for larger corporate environments. For that matter, Ubuntu 14.04 is still supported for another two years, and that's still upstart.

Small warning: Ubuntu's "do you want to upgrade" popup window defaults to "yes". Had to find that out the hard way when a user hit Enter the wrong moment and was suddenly sitting in front of a bricked system.

Usually you press Enter to accept things and ESC to cancel. Also, it first downloads all packages before upgrading, so you should've had time to cancel it.

There were some issues with earlier Ubuntu/Linux/BIOS versions, but most have disappeared with new releases. The last one is a palm detection issue with the touchpad, but it should to be fixed in 16.04. And if you can't wait, at least you can fix things yourself if you want.

Notes from my 15.10 -> 16.04 upgrade: 1) If you use the nvidia drivers from the graphics-drivers PPA, starting the default non-root X server will hang with no graphics output.

Yeah, we've seen similar issues with runC on point 2. I don't think it's an upstream kernel issue as it didn't happen on openSUSE Tumbleweed when we had 4.4 (we're on 4.5 now). So presumably it's some patch Ubuntu applies.

Is an update from 14.04 painless or would you recommend reinstalling? I'd like some newer packages but don't really feel like setting up the whole system again with a reinstall.

maaarghk 10y ago
Pretty painless - I've just ran this on two servers (not in production): sudo do-release-upgrade or if you're on a server sudo do-release-upgrade -d although they don't recommend doing that on a production server because the .1 release usually has a lot of bugfixes. It took about half an hour followed by a reboot. Occasionally had to intervene to tell it to overwrite config files I hadn't touched or to let me do a merge if I had. Obviously make sure you have backups first.
majewsky 10y ago
If you don't feel a particular urge to upgrade right now, it's probably not a bad idea to wait for the first service pack (16.04.1), which usually comes a few months later. Most kinks should be ironed out by then.
Rezo 10y ago

pkaye 10y ago
I always wait a month before upgrading/reinstalling. I have done upgrades in the past through multiple versions and they generally go smoothly but there might a minor glitch or two that requires manual intervention to fix (usually solved though search google for advice.) Another thing I've done is keep /home on a separate partition so I can nuke everything else for a clean install if needed. In such cases, I backup the /etc directory beforehand to recover configuration details as needed.

- takno 10y ago
  I'd guess that Firefox is a fairly good candidate for this kind of packaging just because it has relatively few external dependencies, and lots of Mozilla-specific dependencies which are rarely used by other software

- stubish 10y ago
  It will be Firefox, in a sandbox, out of the box.
symtos 10y ago
Using binaries provided by Mozilla is not a good idea (unless they do things differently with the snaps). They are not hardened in any way; ie. no PIE (rendering ASLR pretty much useless), no stack canaries, no relro, ..., making it a lot easier to exploit any given sec-related bug. $ hardening-check ./firefox ./firefox: Position Independent Executable: no, normal executable! Stack protected: no, not found! Fortify Source functions: no, only unprotected functions found! Read-only relocations: no, not found! Immediate binding: no, not found! Absolutely ridiculous given the amount of vulns likely to linger in its codebase. It should also be noted that Firefox is one of the few packages that Canonical keeps aligned with Mozilla releases (even 12.04 LTS has the latest firefox), and: $ hardening-check /usr/lib/firefox/firefox /usr/lib/firefox/firefox: Position Independent Executable: yes Stack protected: yes Fortify Source functions: yes (some protected functions found) Read-only relocations: yes Immediate binding: yes

Say what you will about Canonical, their whimsical naming scheme has helped expand my vocabulary of both obscure African mammals and little-used adjectives.

If somebody needs a Vagrantfile for testing: https://gist.github.com/therealmarv/555f7efc1c55ffa288bca09191e4e705 https://gist.github.com/therealmarv/555f7efc1c55ffa288bca091... but it seems even Ubuntus Server are not speedy today (Atlas server are also slow) (Update) it seems I'm getting an error with it :/ The guest machine entered an invalid state while waiting for it to boot. Valid states are 'starting, running'. The machine is in the 'gurumeditation' state. Please verify everything is configured properly and try again. If the provider you're using has a GUI that comes with it, it is often helpful to open that and watch the machine, since the GUI often has more helpful error messages than Vagrant can retrieve. For example, if you're using VirtualBox, run `vagrant up` while the VirtualBox GUI is open. The primary issue for this error is that the provider you're using is not properly configured. This is very rarely a Vagrant issue.

matt4077 10y ago
Someone else in this thread posted something rather nonsensical about switching to Commodore 64. I was just about to make a guru meditation joke when I saw that someone apparently beat me to it. I'm running 16.04 with the Vagrant/Virtualbox image from atlas. I've tried getting it to work in the google cloud but had no luck there so far (it's possibly just the ssh key injection that failed, haven't had time to investigate).
alyandon 10y ago
If you've recently upgraded to VirtualBox 5.0.18 you might try downgrading to 5.0.16 as I had a similar issue earlier this week.
- therealmarv 10y ago
  I've updated to the VirtualBox 5.0.19 test build which also fixes that. Bad timing for Ubuntu: https://www.virtualbox.org/wiki/Testbuilds https://www.virtualbox.org/wiki/Testbuilds

michaelmior 10y ago

For anyone like myself who isn't a big fan of the Unity interface, check out Ubuntu MATE[0]. The MATE desktop environment is very similar to pre-Unity Ubuntu. It seems like the final 16.04 release hasn't landed yet but I'm sure it will later today. Ubuntu MATE is also one of the derivative distros that has been granted LTS status by Canonical.

edent 10y ago
I'll second that. Mate is amazing. I can also recommend Cinnamon.
- noir_lord 10y ago
  Both are great, Xubuntu is excellent and still my goto since it has pretty much exactly the features I want from a DE. It's nice to have good choices that use the old paradigms. XFCE 4.12 pretty much feels exactly like Gnome 2 towards the end.
- teekert 10y ago
  Ubuntu Mate is also great on the Raspberry Pi. all the GPIO stuff just works as in Raspbian but you get a more modern desktop (using the classical gnome2 layout) and Ubuntu as the base (which to mee means easier setup of things like a mail server.) I'm hoping Owncloud starts to use Snaps.
- satysin 10y ago
  I would love to see an "official" Cinnamon build in the way we have Xubuntu, etc.
blacksmith_tb 10y ago
Or, though not everyone's cup of tea, I quite like Ubuntu Gnome[1], which is aggressively not retro or Unity. 1: http://ubuntugnome.org/ http://ubuntugnome.org/
niedzielski 10y ago
I like some of the features of their window managers but I don't think Xubuntu and MATE have much support for HiDPI yet and, in general, seem to lag behind stock Ubuntu.

> Online searches in the dash are now disabled by default [1] A welcome and saner default. I'm thinking of moving back to Ubuntu from LinuxMint (I was thinking of Arch as well but not too confident of being on the bleeding edge).

Diederich 10y ago
Besides the default online dash searches pre-Xenial, do you mind sharing what other changes are allowing you to consider moving back?
zanny 10y ago
As someone who has used Arch for 4 years, the bleeding edge got boring. I haven't had a major breakage in at least a year, probably longer, unless you count KDE 4 -> 5 being a breakage - one any 14.04 to 16.04 upgrader will also have to contend with. The last major show stopper I can recall was when Arch dropped security hooks from the kernel and I had to get rid of my MAC.
takno 10y ago
I never moved to mint, but I did recommend trying it to some people who really didn't like unity. I pretty much stopped doing that when they had the security issues last year. Is that what is prompting you to look at switching back, or are you just more reconciled to unity in general now?
- dorfsmay 10y ago
  If one wants Ubuntu and GNOME, there's https://ubuntugnome.org/ https://ubuntugnome.org/
- noisy_boy 10y ago
  That is one and I read online (can't find the source now) that Mint development doesn't respect compatibility/play well with other open source developers. I don't know how much of it is true but for me, compatibility is important. For almost 5-6 years, I have never formatted my home directory. So if my distribution is, for example, creating config in a non-compatible fashion, I won't be able to move to another distro. I know that typically distros don't modify individual program's dotfile/config etc but I guess I'm a bit paranoid about it.

Is there any way I can download Ubuntu securely? They don't seem to have an HTTPS link to the .iso file

__david__ 10y ago
You can verify the integrity of your download with the SHA256SUMS file. You can verify that with the SHA256SUMS.gpg file.

lobo_tuerto 10y ago

I wonder why Canonical don't have an HTTPS version for this page.

csense 10y ago

They should just stop publishing MD5SUMS for new releases. By now, everybody should have gotten the word that MD5 has been broken. The security of the MD5 has been severely compromised, with its weaknesses having been exploited in the field, most infamously by the Flame malware in 2012. The CMU Software Engineering Institute considers MD5 essentially "cryptographically broken and unsuitable for further use". [1] [1] https://en.wikipedia.org/wiki/MD5 https://en.wikipedia.org/wiki/MD5

pritambaral 10y ago
They do provide SHA256SUMS. I guess MD5SUMS are there for legacy purposes. It is on users to stop using MD5SUMS and move to SHA256SUMS
thieving_magpie 10y ago
I've always wondered this but felt too embarrassed to ask, screw it. Let's say the ubuntu 16 iso is infected with some kind of malware by a 3rd party. If they have control of the file, would they not have control of the checksum displayed on the site? I can understand if the checksum is spread to other sites for cross-reference but I'm having trouble seeing why a checksum from the same location as the file you're downloading is worth anything. Any insight?
- defective 10y ago
  It's worth it for error-checking.
- eloisant 10y ago
  If they infect at the source, yes. But if just one mirror is infected, or one of the CDN servers, the attacker may not be able to change the checksum on the official site.
  - thieving_magpie 10y ago
    Ah - that makes sense. I knew their had to be an easy answer but I couldn't see it. Thanks

PSA: If you're running a HTTP/2 server like NGINX on the 14.04 LTS you'll want to upgrade to this release. Google Chrome will no longer support HTTP/2 on vanilla 14.04 after May 15th [0], even if you're using the latest official upstream NGINX packages. This is because 14.04 ships with a version of OpenSSL that does not support the ALPN extension (prior to OpenSSL 1.0.2 you're limited to NPN, now deprecated). There was a bit of back-and-forth about the exact date, as the change was originally scheduled for earlier. However, Chrome decided to specifically push back the date so that there would be an Ubuntu LTS release available with the required support [1]. If you're still stuck on SPDY, that's going to be dropped too, so there's really no good reason not to simply use HTTP/2 at this point.

qznc 10y ago
If you use 14.04, you usually upgrade at the first point release to 16.04.01, not now at 16.04.00. Only 15.10 will immediately suggest an update. Is this outdated or not applicable to servers?
- Rezo 10y ago
  That is correct, upgrades are not enabled between LTS releases at this time, also for servers AFAIK. Either way, personally I would never upgrade a server in place these days. Treat your servers like cattle not pets: Rebuild from new base image, validate, put into LB/proxy, terminate old stack.
  - poooogles 10y ago
    This. Our upgrade path was changing a variable in our packer config. Literally the easiest upgrade ever.
- collinmanderson 10y ago
  You should hold off doing in-place upgrades using "do-release-upgrade" until 16.04.1 (due August/September). However, you can also "upgrade" your stack by building a new image using 16.04 from scratch, and that doesn't need to wait until 16.04.1.

From some sources, I've heard that it appears that those with AMD graphics will suffer a downgrade in performance until the point release in June. I think by June, the open source AMD drivers should be up to speed or have the same features as the previous flgrx ones. From what I gather it's more like a downgrade in supported features. I think this is just an issue if you are doing 3D graphics work or gaming.

fulafel 10y ago
Most people with AMD graphics have been using the open source drivers and will just see all around improvements. edit: Also, you can get Vulkan with the new drivers.
- rleigh 10y ago
  This very much depends upon whether you want the latest OpenGL 4.x features or not. Compute shaders, etc. Most people won't notice, but if you want to develop or use applications using these features, the open drivers aren't yet up to par, so for these cases it is indeed a major downgrade.
  - chippy 10y ago
    So to be more accurate, its more developing with these graphics functions, rather than gaming? games developing vs games playing.
  - tormeh 10y ago
    Only temporarily. The closed source ones are legacy now, afaik. I believe AMD has said they want to only use open source drivers with closed source plugins; i.e. hybrid drivers. Anyone know if it's going to be the same on Windows? Open source with proprietary plugins?

If I have a software RAID that I created under MINT using `mdadm`. will the partition work the same after installing Ubuntu 16.04 or will I have to re-synch the volumes?

e12e 10y ago
AFAIK mdadm has been stable for years (one of the reasons why I prefer software raid to hardware raid). As long as you boot into anything resembling a recent Linux kernel along with a userspace with mdadm support, you should be fine. If in doubt, boot from a live-cd/usb and see if you can mount your drives ok.

I gotta say, Canonical/Ubuntu has a lot of respect in my book for how dependable the distro has been over the years. I've been through my fair share of distros, and one of my employees goes through a new Linux install at least once a week. Ubuntu is one of the few distros that almost always works. Other distros will have one problem or another with this machine or that, but put Ubuntu on there and everything is fine (well, as fine as Linux gets). A few weeks ago I had to dig up an old 12.04 machine and bring it back to the modern age. Much to my surprise, I was able to upgrade it all the way to 15.10 with minimal hassle. While the normal apt repos were dead for 12.04, Canonical keeps around an archived mirror. So you just edit the sources file to point at the archive, and then you can upgrade from there. Impressive. Not that Canonical/Ubuntu don't have their warts. The Amazon fiasco, Unity, their cloud services, etc. And at the end of the day it's still Linux, with all the problems that brings. But, all things considered, I rate Ubuntu as the best of the bunch and feel grateful for the gift they give to the community.

paulddraper 10y ago
Yeah, take Ubuntu and their repos, throw out Unity, find a way to get a Java release from the last few years, do the graphics drivers dance, and you have a very solid, reasonably compatible development environment.
