Public bug reported: I tried updating from ubuntu 18.04 to 20.04. It gave errors previously saying that third party applications were causing problems and then the it stopped midway. I turned off the repositories of third party apps in Software and updates. This time it just stated that 'Could not calculate the upgrade. An unresolvable problem occurred while calculating the upgrade.'
