Title:
  18.04 to 20.04 upgrade failure

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

Bug description:
  A question in Nov 2020 appeared in
  http://answers.launchpad.net/ubuntu/ :

  694046  not able to upgrade to 20.04 fm 18.04 Could not calculate the
  upgrade An unresolvable problem occurred while calculating the
  upgrade.

  I have the same problem for months now. His question was not resolved.
  Hope the bug is fixed because in April 2023, 18.04 will be obsolete.
  Might need to buy a new computer and OS.

  Both of us may not the most computer literate. Or haven't been
  answered.

  Thank you.
