[Bug 1356270] Re: update from 13.10 to 14.04 failed

Reviewing the files from your upgrade attempt you seem to have enabled a
PPA that provides Xorg packages. 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 for the xorg-edgers
PPA.  Instructions for reverting to official Xorg packages should be
similar for the PPA that you have enabled.

Title:
  update from 13.10 to 14.04 failed

Status in “ubuntu-release-upgrader” package in Ubuntu:
  Invalid

Bug description:
  When updateing from 13.10 to 14.04 the update stops with this error:
  Es konnte nicht ermittelt werden, welche Systemaktualisierungen verfügbar sind

  Ein unlösbares Problem trat beim Berechnen der Aktualisierung auf.

   Dies kann verursacht worden sein duch:
   * Aktualisieren auf eine Vorabversion von Ubuntu
   * Verwendung der aktuellen Vorabversion von Ubuntu
   * Inoffizielle Softwarepakete, die nicht von Ubuntu bereitgestellt wurden

  Falls nichts von dem zutrifft, melden Sie diesen Fehler bitte, indem
  Sie den Befehl »ubuntu-bug ubuntu-release-upgrader-core« in einem
  Terminal ausführen.
