Ich habe richtigen Internetzugang und meine aktuelle IP (in Großbritannien) lautet, 82.47.29.14aber mein Laptop ist immer noch mit dem deutschen Server verbunden 91.189.91.24 80.
Aber jetzt kann ich Folgendes nicht tun do-release-upgrade:
alvas@ubi:~$ sudo do-release-upgrade -d
Checking for a new Ubuntu release
Err Upgrade tool signature
