Jitsi Meet install on a Raspberry Pi 4 with Ubuntu Server 20.04

This guide helps you host your own Jitsi server on a Raspberry Pi 4B. It is adapted from Jitsi's quick install guide and the Jitsi on ARM guide written by crouchingtigerhiddenadam. The biggest difference is this is designed to work with a Pi running Ubuntu Server 20.04 instead of Raspbian.

I did this because I'd rather set up Jitsi Meet on a Raspberry Pi I already own than add a dedicated VPS (and pay AWS's bandwidth costs) just for that. I used Ubuntu 20.04 because I'm more familiar with Ubuntu than with Raspbian, and using an arm64 OS makes the setup easier than on armhf. I also tried to use distribution packages instead of manually downloading individual deb files throughout.

	Fixing jack audio on ARM Ubuntu 14.04

	Install prerequisite packages:
	$ sudo apt-get build-dep jackd2

	Install the source package:

	$ apt-get source jackd2

	Downloads the source into the current directory and applies the Ubuntu

	// for example, if we have a mp3 at "audio/tuba@7/01.mp3"

	var test = new Tone.Player("audio/tuba@7/01.mp3").toMaster(); // load and connect

	test.retrigger = true; // enable retrigger

	test_srcs = []; // prepare an array to keep track of sounds..

	test_srcs.push(test.start()._source); // start playbacks and collect their '_source's..
	test_srcs.push(test.start()._source);

	# First su in as root
	sudo su

	# Then set fan control to manual mode
	echo 1 > /sys/devices/platform/applesmc.768/fan1_manual

	# Then set the fan speed to any value between fan1_min and fan1_max. To view these values
	cat /sys/devices/platform/applesmc.768/fan1_min
	cat /sys/devices/platform/applesmc.768/fan1_max
