I am trying to upgrade a 21.10 xubuntu system to 22.04. When I try 'do-release-upgrade' I see the following:-
root@t470# do-release-upgrade Checking for a new Ubuntu release Your Ubuntu release is not supported anymore. For upgrade information, please visit: http://www.ubuntu.com/releaseendoflife
Please install all available updates for your release before upgrading. root@t470#
There is one 'held back' package which I think my be causing my problem, I can't 'unhold' it now though as the repositories are not available.
Help!
