I'm following a guide from wilsonet.com, and I get to this part and get stuck. I type it in, it processes and downloads everything, but then near the end of the process this happened:

arning: rpmts_HdrFromFdno: Header V3 DSA signature: NOKEY, key ID e42d547b

The GPG keys listed for the "Fedora Core 4 - i386 - Base" repository are already installed but they are not correct for this package.
Check that the correct key URLs are configured for this repository.


Can anyone tell me what I'm doing wrong/what I need to do to fix it now?
thanks
