Title:
  sudo do-release-upgrade -d -f DistUpgradeViewGtk3 failed early

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

Bug description:
  There are no ppa's installed.
  It was a new 20.10 installation a few days ago.

  In an early phase I get this message (translated from German):

  Could not determine which system updates are available

  An unsolvable problem occurred during the system update calculation.

   It was probably caused by:
   * Unofficial software packages that are not provided by Ubuntu.
  Please use the tool "ppa-purge" from the ppa-purge-
  package to remove software from a Launchpad PPA and try to
  try the system update again.

  If none of these apply, please report the bug using the command
  'ubuntu-bug ubuntu-release-upgrader-core' in a terminal. If you want
  to investigate this yourself, see the log files at "/var/log/dist-
  upgrade" for system upgrade details. In particular, look at "main.log"
  and "apt.log".
