Download for Ubuntu 15.04 from 14.10 does not work

[Max]

Nvidia-331 failure on my computer has seem to corrupted everything involving anything that could fix the problem. I can no longer install or delete software, OpenGL no longer works, and I can not change drivers. Now I updated from 14.04 to 14.10 but that only seemed to make the problem worse because now when I try to update to 15.04 it comes up with an error message saying that it can no longer continue the update. I am currently on the 14.10 version of Ubuntu.

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.
