Public bug reported: I'm on Ubuntu 18.04 and I wanted to upgrade to Ubuntu 20.04. But from the upgrade calculation, an error message occurred :
Upgrade error message (18.04 to 20.04): An unsolvable problem occurred during the upgrade calculation. This was probably caused by unofficial software packages that do not come from Ubuntu.
