I am having difficulties finding the gpg pubkey needed to verify the signed .deb and .rpm package (https://github.com/ubccr/mokey/blob/main/.goreleaser.yaml#L46-L51).

From where can I download that public key (in my case because I would like to verify the .rpm)?

FWIW, I looked in all of

• a checkout of this repo
• the list of assests of each release at https://github.com/ubccr/mokey/releases
• http://pgp.mit.edu/, searching for 20b36175d1134b65
• gpg2 --recv-keys 20b36175d1134b65
