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.
