Title:
  sudo do-release-upgrade -d crashes but no errors are shown on the
  termina

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

Bug description:
  I think the crash report has all the details.  I did a full upgrade to
  make sure everything was up to date on my XUbuntu 24.04.4 LTS.  I
  rebooted, logged in and then ran sudo do-release-upgrade -d.  It
  seemed to download everything just fine and then simply crashed out.
  I captured the messages below before I had to close the - hmmm I'm
  going to say tty as I didn't have to close the terminal.  It said x to
  destroy or r to resurrect window.

  Here is the message I captured.

  Could not calculate the upgrade

  An unresolvable problem occurred while calculating the upgrade.

  command 'ubuntu-bug ubuntu-release-upgrader-core' in a terminal. If 
  you want to investigate this yourself the log files in 
  '/var/log/dist-upgrade' will contain details about the upgrade. 
  Specifically, look at 'main.log' and 'apt.log'.
