How do I find gpg keys for certain repositories?
 

What is the easiest way to find the gpg keys or whatever for some repositories that require them. I've found that some people post their sources.list files in these forums with no keys to use for authentication puposes.

# gpg --keyserver wwwkeys.eu.pgp.net --recv-keys XXXXXXXXXXXXXXXX
# apt-key add /root/.gnupg/pubring.gpg
# aptitude update

Replace XXXXXXXXXXXXXXXX with the key required

The thing is that I have no key to start with. So therefore I can't, "Replace XXXXXXXXXXXXXXXX with the key required".

When you do an apt-get update, gpg will complain about the key missing and quote the key. Just replace XXXXXXXXXXXXXXXX with the last eight characters of that key.

Ok.Cool. Thanks.
