Title:
  ubuntu upgrade failed because of unnoficial software packages

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

Bug description:
  1) Ubuntu 18.04.5 LTS
  2) N/A
  3) I expected the upgrade from Ubuntu 18 to Ubuntu 20 would go smoothly
  4) Received a error message stating "Could not calculate the upgrade" and that it was most likely caused by "Unofficial software packages not provided by Ubuntu". Both were confusing.
