Public bug reported:
I tried to upgrade from 18.04 to 20.04 per Ubuntu instructions. Upgrade
halted at early stage "Could not calculate the upgrade" with likely
cause said to be unofficial software packages. I tried to remove with
GUI Software & Updates but that did not help. I do not know how to use
ppa-purge tool.
