Jitsi Meet install on a Raspberry Pi 4 with Ubuntu Server 21.04

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 21.04 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 21.04 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.
