Greetings.
I'm not that familiar with mailing lists so I hope I'm posting this correctly.
I was trying to compile Geany with the geany-1.37.1.tar.gz from https://geany.org/download/releases/
However when I downloaded the GPG Signature (geany-1.37.1.tar.gz.sig) and the GPG Key (colombanw-pubkey.txt) and compared them I got a "This key has expired!" warning.
gpg --verify geany-1.37.1.tar.gz.sig geany-1.37.1.tar.gz gpg: Signature made Sun 08 Nov 2020 10:20:32 AM MST gpg: Good signature from "Colomban Wendling ban@ban.netlib.re" [expired] gpg: aka "Colomban Wendling ban@herbesfolles.org" [expired] gpg: aka "Colomban Wendling lists.ban@herbesfolles.org" [expired] gpg: Note: This key has expired!
