  sudo apt install curl gnupg2 ca-certificates lsb-release debian-archive-keyring

  # Import an official nginx signing key so apt could verify the packages authenticity. Fetch the key:

  curl https://nginx.org/keys/nginx_signing.key | gpg --dearmor |
    sudo tee /usr/share/keyrings/nginx-archive-keyring.gpg >/dev/null

  # Verify that the downloaded file contains the proper key:

  gpg --dry-run --quiet --no-keyring --import --import-options import-show /usr/share/keyrings/nginx-archive-keyring.gpg

  # The output should contain the full fingerprint 573BFD6B3D8FBC641079A6ABABF5BD827BD9BF62 as follows:
