I've been trying to install the openoffice update for the last several days. Every time, it fails due to bad gpg signatures. Has anyone had a successful download and, if so, what Fedora mirror did you use?
Have you delete the previous files from /var/spool/up2date ?
Perhaps have made the first download before the end of the mirroring cycle (it's a big update).
Download made from kernel.org without problem for me.
Cordialy.
