Vor kurzem erschien in der Menüleiste meines Dell XPS 13-Laptops ein rotes Warndreieck. Wenn ich das Menü öffne, wird mir angezeigt, dass „Update-Informationen veraltet sind“.
Ich kann „Nach allen Updates suchen“ auswählen. Daraufhin wird ein Fenster mit dem Namen „Cache aktualisieren“ geöffnet. Ich zeige unten den endgültigen Inhalt, der Lesbarkeit halber verschönert.
Mir sind keine Probleme mit meiner Internetverbindung bekannt und ich hätte diese Nachricht ohne Internetverbindung nicht veröffentlichen können.
Was kann ich tun, um diese Probleme zu lösen?

Deaktivieren Sie nicht unterstützte Update-Systemeinstellungssoftware und aktualisieren Sie Backports! ... überprüfen Sie Ihre Repositories . /etc/apt/sources.list
Opera entfernen:
sudo apt-get purge opera-stable
sudo apt-get update
sudo apt-get clean
sudo apt-get update
sudo apt-get upgrade
Installieren Sie Opera:
sudo apt-get install opera-stable
Sie verwenden Xenial, aber Ihre Quellenliste enthält Links für Precise. Jessie
Sichern Sie Ihre aktuelle Quellenliste:
sudo mv /etc/apt/sources.list /etc/apt/sources.list.bak
