Wenn ich versuche, mein System zu aktualisieren, erhalte ich folgende Warnungen:
W: GPG error: http://archive.canonical.com vivid Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 40976EAF437D05B5 NO_PUBKEY 3B4FE6ACC0B21F32

Ich habe versucht, fehlende Schlüssel mit folgendem hinzuzufügen:
sudo gpg --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys KEY_VALUE
Ich habe die folgende Nachricht erhalten:
gpg: requesting key C0B21F32 from hkp server keyserver.ubuntu.com
gpg: key C0B21F32: "Ubuntu Archive Automatic Signing Key (2012) <[email protected]>" not changed
gpg: Total number processed: 1
gpg: unchanged: 1
Ich habe auch diese Lösung ausprobiert:
sudo apt-get clean
cd /var/lib/apt
sudo mv lists lists.old
sudo mkdir -p lists/partial
sudo apt-get clean
sudo apt-get update
Aber ich erhalte immer noch die obige Warnung.

Dies passiert, wenn ein Spiegelserver nicht vollständig aktualisiert wurde.
Sie können es später versuchen oder zu einem anderen Spiegel wechseln in
Systemeinstellungen -> Software & Updates.
