cURL is a very commonly used program to download individual files from the command line and worth installing to have it around in the future.

sudo apt update
sudo apt install curl

The first command tells your package manager to update its list so you ask for the latest version. You can skip it if you’ve already updated today. The second command tells your package manager to install cURL.

This will happen every now and then, especially when building a package from source. You won’t have some common utility that the documentation writer assumed you had, and you will need to find what package provides it and install the package.
