[Bug 1471437] Re: Upgrade to vivid 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 package version numbers greater than the release to which
you are upgrading. You can revert the PPA by installing the ppa-purge
package from the official Ubuntu archive and then running 'sudo ppa-
purge oibaf'.  After that you try upgrading and again and if it still
fails open a new bug report.  Thanks and good luck!

Title:
  Upgrade to vivid failed

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

Bug description:
  I am using 14.10 and wanted to upgrade to vivid.

  Expectation: It works.

  What I did:

  Before updating I ran apt-get update and apt-get dist-upgrade --fix-missing.
  Then I typed sudo  do-release upgrade in terminal and after confirming that I want to disable potential 3rd party packages I get the following error message (German)

  What happened: Error message

  Es konnte nicht ermittelt werden, welche Systemaktualisierungen
  verfügbar sind

  Ein unlösbares Problem trat beim Ermitteln der Systemaktualisierung
  auf.

  After this, the updater does a rollback.
