[Bug 2066503] [NEW] held packages cause release upgrade to be skipped silently

[Steve Langasek]

Public bug reported:

I have a held package on my system (because the newer upstream version
available in newer Ubuntu releases is unusably broken).  As a result,
update-manager presents me the option to upgrade:

  The software on this computer is up to date.
  However, Ubuntu 24.04 LTS is now available (you have 23.10).

If I choose to 'upgrade', the dialog disappears, and nothing else
happens.

If I run update-manager from a terminal, I see the following output:

  Checking for a new Ubuntu release
  Please install all available updates for your release before upgrading.

But update-manager is a graphical application.  This information should
be shown in the GUI, not on the terminal which is normally not visible
to the user.
