[Bug 2046480] Re: unable to upgrade for no specified reason

[robert marshall]

I tried again a few times in one case removing gir1.2-gdm (see above)
first which removed quite a few other things. Still got a failure. But
today it works and I'm now on 23.10. I guess a fix has also solved this!
Many thanks. This can be closed (wasn't certain what final status to
give it...)!

Title:
  unable to upgrade for no specified reason

Status in ubuntu-release-upgrader package in Ubuntu:

  Could not determine the upgrade

  An unresolvable problem occurred while calculating the upgrade.

  If none of this applies, then please report this bug using the 
  command 'ubuntu-bug ubuntu-release-upgrader-core' in a terminal. If 
  you want to investigate this yourself the log files in 
  '/var/log/dist-upgrade' will contain details about the upgrade. 
  Specifically, look at 'main.log' and 'apt.log'. 

  main.log gives
  ERROR Dist-upgrade failed: 'Broken packages after upgrade: ubuntu-desktop'
  I'd tried it before and was having ppa-purge notifications which I've solved
  I see various broken messages in apt.log (not clear which is causing the problem! or whether it's an observation and the upgrade is solving via the update)the last is:

  Broken ubuntu-desktop:amd64 Depends on gnome-shell-extension-ubuntu-tiling-assistant:amd64 < none @un mH >
