Really great lesson!

it might be better practice to install NVM and install node using NVM and install yarn globally using node.

example code might look something like this:

sudo apt install curl git-core zlib1g-dev build-essential libssl-dev libreadline-dev libyaml-dev libsqlite3-dev sqlite3 libxml2-dev libxslt1-dev libcurl4-openssl-dev software-properties-common libffi-dev

# install NVM
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.38.0/install.sh | bash

# install latest version of nodejs
nvm install node

# install yarn globally
npm install -g yarn

the above can replace the first code block. :)

sudo apt install postgresql-11 no longer works. :)
