[Bug 1893819] Re: Attempting to Upgrade from 18.04.5 LTS to 20.04.1LTS via terminal

[Brian Murray]

Reviewing the files from your upgrade attempt you seem to have enabled a
PPA that provides Xorg and python packages. This will prevent the
upgrade as that PPA contains packages which generate failures when
trying to calculate the upgrade. You can revert the PPA by installing
the ppa-purge package from the official Ubuntu archive and then running
'sudo ppa-purge ppa:oibaf/graphics-drivers'.  After that you can try
upgrading again and if it still fails open a new bug report. Thanks and
good luck!

** Changed in: ubuntu-release-upgrader (Ubuntu)
       Status: New => Invalid

** Tags added: ppa xorg-oibaf-ppa
