I just did a fresh FC4 install on a amd64 from the 64-bit dvd iso. When running up2date from the icon and selecting "update everything" it downloads the first item (selinux-policy-targeted-xxx) and pops up a dialog that says the RPM wasn't GPG signed and wants to know if I feel like continuing anyway. hmm.
Is this a bug in the up2date scripts or are the RPM's really not signed? The up2date config gui comes with the "check GPG signature" pre-checked. This seemed like a good thing, but it if means I need to hit "continue" 30 times between 1-2 minute waits, it is going to get old really fast.
The bug is that up2date is reporting a misleading error message, which should be "unknown signature" rather than "unsigned package".
Fix: # rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-fedora
