I surmise this means that my computer's list of trusted signatures
needs to be brought up to date (actually it may not even exist).  How
can this be done?  A link to info would suffice.

There's nothing wrong with that output.  The warning is
simply telling you that the Fedora key isn't signed by a key
you've marked as trusted.

As an aside, we (the royal we, as in folks in the Fedora
community who maintain the website) should change the
verification step to recommend gpgv rather than the gpg
command.  It would require making the fedora.gpg a
de-armored file, but then it the instructions would be
simpler.

Just as I thought.   So...

How do I mark a key as trusted?  What precautions are needed to be sure that the key should actually be trusted?
