#!/bin/bash

# install SuperCollider 3.8 and sc3-plugins. This will dump the source files in your home directory

mkdir ~/src 

cd ~/src

sudo apt-get install git

git clone --recursive -b 3.8 https://github.com/supercollider/supercollider.git

cd supercollider

This also worked perfectly for me to install 3.9 – just change "3.8" to "3.9". UbuntuStudio 17.04.

I've modified this snippet to work with Ubuntu 20.04, installing Super Collider 3.12. See here: https://gitlab.com/-/snippets/2228292
