Err, for completeness the E: is the error message, the W: is warning

The pgp is Pretty Good Privacy, it's a way of encrypting stuff, to make 
sure you get a copy that hasn't been tampered with by a third party, in 
this case something to do with the distro realease list...

Have you run the "Check this CD" option on the CD?
