Well, what you can do is boot from a live usb stick, mount your drive, move /* to /old/ and install afresh. If everything works as desired, you can move back your /home/user directory or selectively get your home directory back. If you don't like it, move everything back. Then you only need to restore grub, which should be easily doable using a chroot from the live media.
- wpietri 14y agoThanks! Alas, that means I have to deal with a fresh install. Which I may do, but it's not the straightforward things I was hoping for. What I'm really looking for is the sort of upgrade/rollback process I'm used to creating for my production apps. One-button upgrade, one-button rollback. Looks like Ubuntu isn't there yet. I suppose the easy thing is just to get another disk, clone my existing setup, and do the upgrade. If I don't like it, I'll just swap in the backup disk.
