Hi Everyone, Sorry to post right out of the gate but I'm having problems running yum upgrade on a new centos 3.4 install. I performed a minimal install of centos, this means I did a custom install but unchecked everything including cups. Error tells me to clean or rm the file...tried both to no avail. Anyone else run into this issue? How do I get beyond it? The exact error is: Downloading Packages warning: rpmts_HdrFromFdno: V3 DSA signature: NOKEY, key ID 025e513b Error: Could not find the GPG Key necessary to validate pkg /var/cache/yum/update/packages/cups-1.1.17-13.3.24.i386.rpm Error: You may want to run yum clean or remove the file: /var/cache/yum/update/packages/cups-1.1.17-13.3.24.i386.rpm Error: You may also check that you have the correct GPG keys installed Thank you for your assistance.
