    $ gpg --verify turnkey-collabtive-16.1-buster-amd64-vmdk.zip.hash
      gpg: Signature made using RSA key ID A8B2EF4287819B03D3516CCA76231C20425E9772
      gpg: Good signature from "0"

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

    $ sha256sum turnkey-collabtive-16.1-buster-amd64-vmdk.zip
      1fbb2db860a89b1e1970e28aec7c954155ffda3f71cb9490b95c31e2ad26ecc8  turnkey-collabtive-16.1-buster-amd64-vmdk.zip
