[Bug 2111253] Re: Problems when upgrading to 22.04 using ubuntu-bug ubuntu-release-upgrader-core

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:
  Problems when upgrading to 22.04 using ubuntu-bug ubuntu-release-
  upgrader-core

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

Bug description:
  When trying to upgrade to Ubuntu 24.04 via terminal using ubuntu-bug
  ubuntu-release-upgrader-core, I get an error message that stops the
  upgrading. Same is when I try to upgrade via do-release-upgrade, where
  I get the following error

  Could not determine the upgrade

  An unresolvable problem occurred while calculating the upgrade.

  This was likely caused by: 
  * Unofficial software packages not provided by Ubuntu 
  Please use the tool 'ppa-purge' from the ppa-purge 
  package to remove software from a Launchpad PPA and 
  try the upgrade again. 

  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'.
