    $ gpg --verify turnkey-gitea-18.0-bookworm-amd64.iso.hash
      gpg: Signature made using RSA key ID 26147592087C0EDE42143B637761DEBABBCFBA7C
      gpg: Good signature from "0"

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

    $ sha256sum turnkey-gitea-18.0-bookworm-amd64.iso
      176846dc754f43a010708d5d584cd6d0264024803531717fcd79aee701e36b61  turnkey-gitea-18.0-bookworm-amd64.iso
