The New Fedora Signing Key
The Fedora Project recently re-signed all of its packages with a new key. The story regarding the key can be found [here]. The release engineering team can be reached in #fedora-devel (irc.freenode.org) or emailed firstname.lastname@example.org for more information.
Enabling the New Signing Key
Users will need to accept the new signing key the first time updates are downloaded. To accept the key, press 'y' when prompted whether or not to import the signing key by PackageKit.
