Hallo!
Seit heute habe ich mit meinem Laptop Probleme auf Sambafreigaben im lokalen Netzwerk zuzugreifen. Als Nemo hing, dachte ich zuerst, es läge am Server (Ubuntu 18.04 Server), hatte da schonmal Probleme mit schlechten SATA Kabeln. Und tatsächlich gabs da auch ein kleines Problem, das habe ich aber nun behoben. Dennoch scheint CIFS immerwieder die Verbindung zu verlieren (der Laptop ist per Kabel angeschlossen). Auf dem DBus werden Meldungen ausgegeben, mit denen ich nichts anfangen kann:
