To install RTL, you need Node v16. By defaul you will have Node v14 for now. To upgrade:
$ curl -s https://deb.nodesource.com/gpgkey/nodesource.gpg.key | sudo apt-key add -
$ sudo sh -c "echo deb https://deb.nodesource.com/node_16.x focal main > /etc/apt/sources.list.d/nodesource.list"
$ sudo apt update
$ sudo apt install nodejs
