I've been running a mythbuntu machine for the best part of 10 years now. I don't use the MythTV stuff any more but it runs as bit of a quasi home server. Over the years I've set up and configured a LOT of stuff, a lot of it I probably don't even remember. I'd like to keep this machine reasonably up to date but really don't want to do a fresh install and reconfigure everything. Is there a way to migrate the system to something light like say xubuntu and upgrade it to 20.04 without a new install?

At the moment I can't update to 20.04:

phil@htpcserver:~$ sudo do-release-upgrade
Checking for a new Ubuntu release
There is no development version of an LTS available.
To upgrade to the latest non-LTS develoment release 
set Prompt=normal in /etc/update-manager/release-upgrades.

Thanks for any help

  • Is your home in a separate partition or is it in the same partition as root? – To Do May 18 at 11:21
  • Home folder is in the same partition – pssturges May 18 at 23:15
  • I would recommend baking up your data and do a fresh install, but if yo really want to avoid that, create a separate home partition howtogeek.com/116742/…, then do a fresh install of Xubuntu, choose the Something else option and make sure you set the new home partition as your new home. – To Do May 19 at 6:52

Mythbuntu is discontinued since 4 years. You can't upgrade to any flavor of 20.04. You have to do a fresh install.

  • Yeah was hoping to avoid that. Funny though that I was able to upgrade to 18.04 without issue a couple of years ago – pssturges May 18 at 23:17
  • You can still try with: sudo apt update && sudo apt full-upgrade -y && update-manager -cd – NicolasSmith May 20 at 4:12
  • Thanks. Well that does give me the option to upgrade to 20.04 (not quite ready to pull the trigger yet). However it's saying that it's a development release. I thought it was a full release by now? I guess this is the reason its not presented as an option with "sudo do-release-upgrade" yet? I'm thinking if I can update to 20.04 at some point I can then install xfce and remove mythbuntu desktop. Is that a reasonable course of action? – pssturges May 20 at 7:42
  • Don't worry, it's a LTS release, not a Dev release. – NicolasSmith May 21 at 9:39
  • OK great thanks. I'll give it a go – pssturges May 21 at 11:16
