[Bug 1898826] Re: error on do-release-upgrade from 18LTS to 20LTS

Reviewing the files from your upgrade attempt you seem to have enabled a
PPA that provides sane 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:sane-project/sane-git' or 'sudo ppa-purge ppa:sane-project
/sane-release' .  After that you can try upgrading again and if it still
fails open a new bug report.  Thanks and good luck!
