RH 90 Yum Update

["Gary Applin" <gapplin b-e-s-t com>]

Hi,
While trying a yum update on a RH 9.0 install I get the following:


Getting cups-1.1.17-13.3.0.3.i386.rpm
warning: rpmts_HdrFromFdno: V3 DSA signature: NOKEY, key ID db42a60e
Error: Could not find the GPG Key necessary to validate pkg
/var/cache/yum/updates/packages/cups-1.1.17-13.3.0.3.i386.rpm
Error: You may want to run yum clean or remove the file:
 /var/cache/yum/updates/packages/cups-1.1.17-13.3.0.3.i386.rpm
Error: You may also check that you have the correct GPG keys installed

I have imported the keys in the docs, how do I get this missing key
'db42a60e'?

Thanks
