[Bug 1891393] Re: Upgrade to lubuntu 20.04.1 stopped when working on installation and package sources

[Chris Guiver]

Thank you for taking the time to report this issue and helping to make
Ubuntu better.

If you read the release notes for Lubuntu 20.04.1
(https://lubuntu.me/tag/focal/) you'll find

"Note, due to the extensive changes required for the shift in desktop
environments, the Lubuntu team does not support upgrading from 18.04 or
below to any greater release. Doing so will result in a broken system.
If you are on 18.04 or below and would like to upgrade, please do a
fresh install."
