Public bug reported: when trying to upgrade to wily werewolf, I received the following error message: Ein unlösbares Problem trat beim Ermitteln der Systemaktualisierung auf.
Dies kann verursacht worden sein durch: * Aktualisieren auf eine Vorabversion von Ubuntu * Verwendung der aktuellen Vorabversion von Ubuntu * Inoffizielle Softwarepakete, die nicht von Ubuntu bereitgestellt wurden I already uninstalled all packages I had installed, but still I receive this error message. Is there another way to upgrade to 16.04?
