Upgrading to 14.04 not possible.

[Dominic Scheurer]

During upgrading (or trying to) 14.04 from 13.10, I get the error message

"Es konnte nicht ermittelt werden, welche Systemaktualisierungen verfügbar sind" ("It could not be determined which updates are available", my translation)

and the upgrade cannot continue.

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.
