[Bug 2098868] Re: cannot upgrade 22.04 to 24.04, no informative error message

Reviewing the files from your upgrade attempt, you have installed
packages from the deadsnakes PPA. Some of the packages installed are
newer than those in the official archive, which is keeping some python
packages installed which then prevents the upgrade from being
calculated. Please try using the official versions of python3 from the
Ubuntu archive. After that you can try upgrading again and if it still
fails open a new bug report. Thanks and good luck!

Title:
  cannot upgrade 22.04 to 24.04, no informative error message

Status in ubuntu-release-upgrader package in Ubuntu:
  Invalid

Bug description:
  Upgrade stops with: (sorry my system is in Swedish)
  """
  Kunde inte beräkna uppgraderingen

  Ett olösbart problem inträffade när uppgraderingen skulle uträknas.

   Detta orsakades troligtvis av:
   * Inofficiella programvarupaket inte utgivna av Ubuntu
  Använd verktyget "ppa-purge" från ppa-purge-paketet 
  för att ta bort programvara från en Launchpad PPA och 
  försök att uppgradera igen.

  Om inget av detta gäller, rapportera buggen med kommandot "ubuntu-bug ubuntu-release-upgrader-core" i en terminal. Om du vill utreda det här på egen hand kommer loggfilerna i "/var/log/dist-upgrade" att innehålla detaljerad information om uppgraderingen. Se särskilt "main.log" och "apt.log".
  """
  There is no error message in main.log. There are 325 packages with "Failed .." in main.log and 146 packages with "Broken ..." in apt.log so this is very hard to fix manually 
  All 3rd party ppa:s have been disabled
