Upgrade from Ubuntu 20.04 to 22.04


I've been reading a few of the threads on upgrading Ubuntu on Linode. None of the advised options seem great, and I'm struggling to see why the do-release-upgrade method would cause issues.

I run the smallest Linode 1Gb RAM, 25Gb disk as a personal mail and web server (LAMP), and that's about it. Don't even have python to worry about :-) The idea of building another server and moving the configuration and data over just seems crazy and very time consuming.

Are there any other options to do this?

Many thanks

The (very) few times I upgraded my Ubuntu Linode in place worked well for me. The only hitch was the first time when I started the upgrade from an ssh session and the output migrated to the console (lish) in the middle suddenly.

Once I figured that out and started watching the console, everything seemed to be going fine.

All that being said:

  • don't do your upgrade from an ssh session…do it from the console;
  • make sure all your services (web, mail, etc) are stopped before starting your upgrade (if you're at the console, you can count sshd in this list); and
  • take a snapshot or otherwise fully back up your Linode before starting your upgrade (in case something goes wrong, you can get back to your starting point easily).
