Public bug reported: Usolvable Problem: System updates couldn't been determined.
Sorry, actual message might sound different in English. I got the German message: "Es konnte nicht ermittelt werden, welche Systemaktualisierungen verfügbar sind Ein unlösbares Problem trat während der Berechnung der Systemaktualisierung auf. Wenn keine dieser zutrifft, melden Sie bitte den Fehler mithilfe des Befehls 'ubuntu-bug ubuntu-release-upgrader-core' in einem Terminal. Wenn Sie dies selbst untersuchen möchten, finden Sie in den Protokolldateien unter »/var/log/dist-upgrade« Details zur Systemaktualisierung. Schauen Sie sich insbesondere »main.log« und »apt.log« an."
