[Bug 1895838] Re: Error during release upgrade 18.04 to 20.04

Reviewing the files from your upgrade attempt you seem to have enabled a
PPA that provides Xorg packages. This will prevent the upgrade as that
PPA contains package version numbers greater than the release to which
you are upgrading. 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!
