Title:
  cannot calculate upgrade when trying to update form 18.04 to 20.04.1

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

Bug description:
  Cannot upgrade from 18.04 to 20.04. At first I was getting errors
  about conflicting PPAs, once I removed those sources I get the same
  error message saying that the upgrade cannot be calculated, but there
  is no further information given. Doing dist upgrade and apt get -f
  does not address the issue. Not sure how to proceed from here.
