Title:
  Can't upgrade from LTS 18.04 to LTS 20.04

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

Bug description:
  Using the instructions at: https://ubuntu.com/blog/how-to-upgrade-
  from-ubuntu-18-04-lts-to-20-04-lts-today

  > sudo do-release-upgrade -d –allow-third-party

  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'.
