Title:
  Upgrading to new LTS 20 from LTS 18 via command update-manager -d

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

Bug description:
  Description:	Ubuntu 18.04.4 LTS
  Release:	18.04
  Error message says
  This was probably caused by:
    * Unofficial software packages not published by Ubuntu
  Use the "ppa-purge" tool from the ppa-purge package
  to remove software from a Launchpad PPA and
  try to upgrade again.

  I am trying to upgrade to new LTS using terminal command update-manager -d
  I've installed ppa-purge and tried using it but I can't seem to figure out which to package to remove. I've tried looking in the logs but the issue "escapes" me
