[GTALUG] Ubuntu update 19.10 -> 20.04?

[Stefan Kloppenborg]

My understanding is that Canonical maintains two branches of releases. The even numbers are the LTS releases, the odd are the other ones (I'm not sure what they call them). When you're on a LTS version, do-release-upgrade will by default only look for a newer LTS versions. Similarly, when you're on an odd version, do-release-upgrade will only look for another odd numbered version. You can override this behavior, though. I recall seeing some instructions for doing this through the GUI in the 20.04 release announcement a few weeks ago.

A quick internet search seems to indicate that to upgrade from 19.10 to 20.04, you can run `update-manager -d`. The man pages indicate that `do-release-upgrade` has the same flag. I've always run the LTS versions, so I've never personally done this. So, there may be nuances that I don't understand. In any case, you should do a bit of research before executing a shell command that some random person posted to a mailing list.

Hope this helps.
