Well that message is pretty self-explanatory. :)  This commonly happens
when someone is mistaken about which keys they have, and/or where those
keys are located. This leads to you having the wrong public key. Have
the person do whatever the PGP equivalent to 'gpg --list-keys' is and
then you should be able to sort it out from there.
