[Bug 2003594] Re: Couldn't upgrade from 18.04.6 LTS to 22.04 LTS

Reviewing the files from your upgrade attempt, you have installed nodejs
from the nodesource PPA. This version of nodejs is greater than the one
in the official archive and is keeping some packages installed which
then prevents the upgrade from being calculated. Please remove nodejs
along with any other packages from that archive and disable the archive.
After that you can try upgrading again and if it still fails open a new
bug report. Thanks and good luck!

Title:
  Couldn't upgrade from 18.04.6 LTS to 22.04 LTS

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

Bug description:
  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.

  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'.
