Comment 24 for bug 1069133

This is what they sent me... And it worked great. Thanks!
Reviewing the files from your upgrade attempt you seem to have enabled
the xorg-edgers-ppa. This will prevent the upgrade as that PPA contains
different versions of packages essential to Ubuntu. The page,

ppa <https://launchpad.net/~xorg-edgers/+archive/ppa>, contains details on
to
how to revert to the official Xorg packages. Thanks.
 Hi !

I face the same issue for upgrading 13.10 to 14.04... I fiddled around
the repositories, and upgrade commands, with no success... Is there a
straightforward process to get this working ? :/

Bye,
Yann
