Public bug reported: Ubuntu 18.04.5 LTS upgrading to latest LTS version. Expecting the upgrade to proceed or at least give me a useful error, however it doesn't display an error. Instead it just states "Could not calculate the upgrade. An unresolvable problem occurred while calculating the upgrade. If none of this applies report the bug. Since there is no problem listed with the error message, I would expect one to be listed. Since none of the error does apply (nothing listed) I'm reporting it as a bug.
