repository keys invalidated--can't access all updates and packages

I don't know how, but my system says the gpg signatures are invalid. This is preventing me from re-installing grub so I'm in kinda a tight spot. I do realize this is more a problem for the IRC, but its been pretty dead the last few hours.

I do not know if this qualifies as a security problem, but because packages cannot be counted on to update it could be.
