[Bug 2010069] Re: Trying to upgrade from 20.04 to 22.04.

[Giuseppe D'Angelo]

I've got an identical problem.


* Removed all 3rd party packages; and removed the corresponding sources.list entries
* apt list '?obsolete'    => returns nothing
* No package is manually hold (apt-mark showhold is empty)


Still the upgrade fails with the same error message:


2023-03-10 16:41:43,623 DEBUG Marking 'ubuntu-desktop' for upgrade
2023-03-10 16:41:43,744 WARNING Can't mark 'ubuntu-desktop' for upgrade (E:Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.)
2023-03-10 16:41:44,001 ERROR Dist-upgrade failed: 'Broken packages after upgrade: evolution-data-server, gnome-control-center, libgirepository-1.0-1, ubuntu-desktop'


Just to exclude the possibility that there is some broken package
installed, is there a way to check that all the packages on my system
are *official* packages? (Basically, coming from Ubuntu, and each one at
the "expected version" and not some broken version somehow, that would
impede the upgrade).
