I keep getting the following error when running "yum -y update" on a Redhat 9 laptop: warning: rpmts_HdrFromFdno: V3 DSA signature: NOKEY, key ID 8df56d05 Error: Could not find the GPG Key necessary to validate pkg /var/cache/yum/fedora-stable/packages/nmap-3.30-0.fdr.1.rh90.i386.rpm Error: You may want to run yum clean or remove the file: /var/cache/yum/fedora-stable/packages/nmap-3.30-0.fdr.1.rh90.i386.rpm Error: You may also check that you have the correct GPG keys installed I trie4d removing the file named and the problem happened on another package. I then ran "yum clean" and the problem happened again. How do I address this issue? As an aside, I also installed apt-get to see if that worked and it also failed on the keys. Ben Ricker Wellinx, inc.
