New Fedora Update Problem

OK, I got through the update, but got the following error messages at the end:

The FAQ described what to do:
>blockquote>Edit /etc/yum.repos.d/fedora.repo and replace the line
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-fedora
with:
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY

Which I did, but no joy.
What now?
