Ich möchte mein 18.04.6 LTS auf das nächste LTS aktualisieren, aber es lässt mich nicht, weil es denkt, dass es Updates gibt, die ich zuerst durchführen sollte. Diese Updates funktionieren jedoch nicht und geben die Fehlermeldung „Überprüfen Sie Ihre Internetverbindung“ aus. Ich denke, weil sie jetzt nur noch als erweiterter Support verfügbar sind.
Ich habe versucht, /etc/apt/sources.list zu ändern, um old-releases.ubuntu.com zu verwenden, aber es scheint nicht zu helfen.

Okay, ich schätze, es war ein Fehler von mir, meine /etc/apt/source.list in old-releases.ubuntu.com zu ändern, und es hat nichts geholfen, aber als ich die unteren 4 oder 5 davon in der GUI abgewählt habe, wurde das Upgrade plötzlich freigeschaltet.
Man fragt sich, ob es genauso gut funktioniert hätte, wenn man von Anfang an einfach alle Quellen deaktiviert hätte, aber leider kann ich das nicht mehr testen.
Das Upgrade scheint problemlos verlaufen zu sein.
