Title:
  upgrade from ubuntu18.04 to 20 fails

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

Bug description:
  I am on ubuntu 18.04.2 LTS, when i run sudo do-release-upgrade -d i
  get the following message:

  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'.
