apt-get gpg key updates

From time to time the GPG keys contained in apt-get expire or need to get renewed. To accomplish this simply use gpg --export 010908312D230C5F -a | apt-key add -

Replace 010908312D230C5F with whatever key id is needed. If the key with key id 010908312D230C5F is not in your gpg keyring you need to import it from a keyserver first: gpg --recv-key 010908312D230C5F

PS: I am really unsure where the information that the keys need to be updated is announced. Maybe there is a feed or mailing list out there??
