While verifying my download of Fedora-34, I encounter this message:
$ gpg --verify-files *-CHECKSUM 
gpg: Signature made Fri 23 Apr 2021 12:36:44 PM PDT
gpg:                using RSA key 8C5BA6990BDB26E19F2A1A801161AE6945719A39
gpg: Good signature from "Fedora (34) <fedora-34-primary@fedoraproject.org>" [unknown]
gpg: WARNING: This key is not certified with a trusted signature!
gpg:          There is no indication that the signature belongs to the owner.
Primary key fingerprint: 8C5B A699 0BDB 26E1 9F2A  1A80 1161 AE69 4571 9A39
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.
