Bearbeiten: Manchmal werden zusätzliche Nachrichten an die obigen Nachrichten angehängt:
W: GPG error: http://www.duinsoft.nl debs Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY E18CE6625CB26B26

E: Some index files failed to download. They have been ignored, or old ones used instead.
