    $ gpg --verify turnkey-mumble-17.1-bullseye-amd64.iso.hash
      gpg: Signature made using RSA key ID E10F65670C8EBE42ED0C3A49CCA51174468F9073
      gpg: Good signature from "0"

2. Recalculate the image hash and make sure it matches your choice of hash below.

    $ sha256sum turnkey-mumble-17.1-bullseye-amd64.iso
      5c0393a570d55729139a36923c4a294f426473f5d95b6ce9f2be3cd80beb55d9  turnkey-mumble-17.1-bullseye-amd64.iso

    $ sha512sum turnkey-mumble-17.1-bullseye-amd64.iso
