<p>If you don't already know how to do this, then you should probably not be attempting to work on the troggle code. But in case you are an experienced linux user who has always had someone else set up the system for them, then Ubuntu is the easiest and more forgiving to install, either directly on the computer or inside WSL.

<p>Python is not installed by default usually, and in any case we need specific versions to be installed. For Ubuntu 20.04 the default is python3.9 but this is incompatible with standard debian Buster which is what is live on our server, so we also need python3.7 . If you are planning on helping the migration of troggle from debian Buster (v10) to Bullseye (v11) then you will also want python3.8 .
