apt-get Errors

If you get the following error while updating the package list:

W: GPG error: jaunty Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 632D16BB0C713DA6

You need to manually update the key. The key-ID is the last 8 digits of the key, in this case: 0c713da6.

Now fetch the key from the Ubuntu keyserver:

gpg --keyserver --recv 0c713da6

And finally add the new key to the apt-keyring:

gpg --export --armor 0c713da6 | sudo apt-key add -

You can even automate this a bit with the following shell script:

gpg --keyserver --recv $KEYID
gpg --export --armor $KEYID | sudo apt-key add -

This will only use the last 8 digits of the first parameter as KEYID. So you can even call it with the full 16 digits.
