Comment 8 for bug 11259

Thanks for this additional information.
When I verify the signature of the attached Release.gpg file (with
gpg --verify --keyring /etc/apt/trusted.gpg Release.gpg Release), I get the output:

gpg: Signature made Fr 17 Dez 2004 17:34:12 CET using DSA key ID 437D05B5
gpg: BAD signature from "Ubuntu Archive Automatic Signing Key
<email address hidden>"

The date (17.12) is way too old. The signature should be only some hours old. I
would
love to know if your problem goes away if you tell apt not to use the proxy (if
possible).

thanks,
 Michael
