[Bug 1450633] Re: cannot upgrade to 15.04

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