Either something got screwed up at Red Hat or somebody cracked something. Specifically, I'm trying to install PSGML via Yum on FC4. It looks like the PSGML is not signed with the correct Fedora key. I have verified the 0x4F2A6FD2 key as correct on the Fedora website, so it looks like all that is installed correctly. PSGML is apparently signed with a key ID of db42a60e. Here's the Yum console transcript. -- Dave Setting up Install Process Setting up repositories updates-released 100% |=========================| 951 B 00:00 extras 100% |=========================| 1.1 kB 00:00 base 100% |=========================| 1.1 kB 00:00 Reading repository metadata in from local files Parsing package install arguments Resolving Dependencies --> Populating transaction set with selected packages.
