[Bug 2111780] Re: Upgrading to 22.04 from 20.04 it is failing

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:
  Upgrading to 22.04 from 20.04 it is failing

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

Bug description:
  When I upgrade from 20.04 to 22.04.

  I get the following error.

  
  Could not calculate 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.
