[Bug 1910842] Re: upgrade to 20.04 failed

[Brian Murray]

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:kisak/kisak-mesa'.  After that you can try upgrading again and
if it still fails open a new bug report.  Thanks and good luck!
