This was caused by an incorrect version number used for a python-ldb
security update (see bug 2009895), and has since been resolved.

Bug description:
  Sorry in advance if this is not bug or a duplication, I mainly follow
  the instructions in hope that it helps

  I was trying to upgrade the ubuntu version. Firstly form 18 to 20, which went successfully.
  That after the reboot started to try to upgrade from 20 to 22 which resulted in the error, that suggests no action but to report the error here.

  the command I was running was `sudo do-release-upgrade`

  Could not calculate the upgrade

  An unresolvable problem occurred while calculating the upgrade.

  If none of this applies, then please report this bug using the

  you want to investigate this yourself the log files in
  '/var/log/dist-upgrade' will contain details about the upgrade.
