Public bug reported: I have tried to perform an upgrade to Ubuntu 18.04.1 LTS where the process failed on step 2 "New package sources are set up" ("Neue Paketquellen werden eingerichtet"). There appears a message box telling me that it could not determine which system updates would be available ("Es konnte nicht ermittelt werden, welche Systemaktualisierungen verfügbar sind").
