[Bug 1611197] Re: Upgrade from 14.04 LTS to 16.04 LTS failing

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 oibaf'.  After that you try upgrading and again and if it still
fails open a new bug report.  Thanks and good luck!
