Getting linux up with vnc from macOS:

Launch a Ubuntu 20.04 LTS Server as an EC2 instance, and ensure you have a security group that allows you to access it via SSH (and SSH only, you'll be using SSH to port tunnel VNC).

Once you've got the instance up, and have ssh'd in, run the following to install the packages necessary for a basic desktop environment (not included by default in the Ubuntu server install on AWS).

sudo update
sudo apt install ubuntu-desktop
sudo apt install tightvncserver
