[rhn-users] many packages fail PGP-signature

[Jaap Bril]

My fedora machine keeps telling me it has updates available. As a matter of 
form I try and keep this machine up to date. The annoying thing is that many 
(up to 41 now) packages including the newest kernel do not pass the 
PGP-signature test. 

It could of course be the connection, but as I NEVER had this problem with my 
RHEL stuff that seems not to be the case.

What's happening and (more important) could someone correct the problem?

TIA
