Error Updating Webmin

When I try to update Webmin I get the following error:

warning: rpmts_HdrFromFdno: Header V3 DSA signature: NOKEY, key ID a0bdbcf9
Public key for webmin-1.360-1.noarch.rpm is not installed
Retrieving GPG key from file:///etc/pki/rpm-gpg/RPM-GPG-KEY-virtualmin
GPG key at file:///etc/pki/rpm-gpg/RPM-GPG-KEY-virtualmin (0xA0BDBCF9) is already installed

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

The same thing is occurring with CentOS 5 and RHEL 5
