Once that archive is enabled the package can be installed directly:
```shell
$ sudo apt install guardctrl
$ sudo apt install guardian guardctrl
```
The `guardctrl` package depends on `guardian` package, so you'll automatically get them both. guardctrl will install the command line interface, as well as all the needed systemd service unit files.
