[Bug 2095232] Re: update-manager is marked for removal but in the removal deny list

Marking as a duplicate of bug #2084610, which describes the same
upgrader failure ("update-manager marked for removal but in the removal
deny list") on the same package version (ubuntu-release-upgrader-core
1:22.04.20) and is the oldest report of the two

Note for #2084610: This bug report contains the most diagnostic actual
upgrader debug log lines:

  DEBUG Marking 'ubuntu-desktop' for upgrade
  WARNING Can't mark 'ubuntu-desktop' for upgrade (E:Unable to correct problems, you have held broken   packages.)
  DEBUG denylist expr 'update-manager$' matches 'update-manager'
  DEBUG The package 'update-manager' is marked for removal but it's in the removal deny list

So the underlying cause appears to be that the upgrader fails to mark
ubuntu-desktop for upgrade (due to held broken packages), and the
cascading attempt to remove update-manager then hits the denylist regex.
