I've upgraded from 18.04 in the past, but via intermediary LTS releases (i.e. 20.04). Going all in one step is not possible IMO. Also note that Ubuntu LTS releases only do upgrades after the first point release of a new version. You won't be upgraded to 21.10 until it hits 21.10.1. [edit] Apparently the holdout until point release .1 only applies to LTS versions: > Upgrades from one LTS to the next LTS release are only available after the first point release. For example, Ubuntu 18.04 LTS will only upgrade to Ubuntu 20.04 LTS after the 20.04.1 point release.

I’ve learned that ubuntu upgrades only if you update to the next version as soon as it is released. I have a 14.04 server that I cannot upgrade anymore and it sucks. Also, NVidia and Cuda drivers mess the upgrade path as well. And ubuntu is the most supported distro.

  Yes, Nvidia is special (in a bad way). They seem especially hell-bent on pushing new versions of CUDA on everyone way before any usable software supports it (i.e. try getting a usable tensorflow or mxnet when your machine auto-upgraded to 11.4.x one day after its release).

    You can have multiple CUDA versions installed at once, it’s not exclusive.

Actually you can upgrade from old releases. You do need to move from LTS to LTS, rather than jumping. So you can upgrade 14.04 to 16.04, then to 18.04, and then to 20.04.
