all you need is the public key from fedora download site. The public key
need to be install to allow update with yum. type the following in the
shell prompt using the root account and password:

[root@lnxfc7 ~]# rmp -Uvh ftp://download.fedora.redhat.com/pub/fedora/

This should install the public key on your machine.

have fun!
