Could not upgrade to 14.04

[Steven McCullagh]

Could not upgrade to 14.04

I think it's graphics related. I performed sudo apt-get remove --purge ppa:xorg-edgers/ppa
But I still get the following errors in apt.log: http://pastebin.com/ATgV8wj7
And this from main.log: http://pastebin.com/wgmee2b1

n.b:

Any advice would be greatly appreciated.

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.
