[Bug 2078442] Re: do-release-upgrade on 22.04 LTS to 24.04 cannot proceed

[Z Unger]

Thank you so much for your help, very much appreciated, especially since
it was self-caused.

I did manage to purge the later-version packages in the meantime, and
running your revised commands confirms the correct versions are now
installed. do-release-upgrade is proceeding as normal now.

Thanks again! Not sure how to mark this issue resolved but please go
ahead if it is on your side.

  Could not calculate the upgrade

  An unresolvable problem occurred while calculating the upgrade.

  The package 'update-manager' is marked for removal but it is in the 
  removal deny list. 

  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'.
