Debian >= Bullseye

  1. If you don't have https transport for apt installed, do that first, since I'll redirect you to https in any case:
    sudo apt install apt-transport-https
  2. Make yourself root:
    sudo -s
  3. Obtain the key:
    wget -O - https://net2o.de/bernd@net2o.de-yubikey.pgp.asc | \
    gpg --dearmor -o /usr/share/keyrings/net2o-archive-keyring.gpg
  4. Create a one-line file for the repo: Set version to either oldstable/stable/testing/unstable, whatever fits your Debian:
    version=testing
    cat >/etc/apt/sources.list.d/net2o.list <<EOF
    deb [signed-by=/usr/share/keyrings/net2o-archive-keyring.gpg] https://net2o.de/debian $version main
    EOF
  5. And then fetch the repository and install
    apt update
    apt install gforth-minos2
  6. Leave root
    exit
