** Description changed: Impact ------ Users who have both the lubuntu-desktop meta package (which depends on xscreensaver) and the ubuntu-desktop meta package install can not upgrade to the next release of Ubuntu. This is because there is a PostUpgradeRemove rule for the xscreensaver package. This rule has been around since at least Dapper and as far as I know is no longer necessary. [Test Case] ----------- 1) On an Ubuntu 18.04 LTS system install both the ubuntu-desktop and lubuntu-desktop metapacakges 2) Run do-release-upgrade -d to upgrade to Ubuntu 20.04 LTS 3) Observe that the upgrade fails to calculate and notice the following in /var/log/dist-upgrade/main.log: 2020-07-20 11:37:59,839 DEBUG Marking 'ubuntu-desktop' for upgrade 2020-07-20 11:38:00,074 DEBUG Marking 'lubuntu-desktop' for upgrade 2020-07-20 11:38:01,181 WARNING Can't mark 'lubuntu-desktop' for upgrade (E:Unable to correct problems, you have held broken packages.) + + To test the version of the dist-upgrader from -proposed you'll need to + download the dist-upgrade tarball and extract it in to /tmp/.

Additionally, the xscreensaver is safe to have installed so there is no chance of regression. Original Description -------------------- Trying to upgrade from 19.10 to 20.04.
