Mostly a note-to-self.
After you’ve installed r-base on Ubuntu with the default packages, you will have issues installing Tidyverse. It’s because there are a bunch of packages missing.
Install them with:
sudo apt install libfreetype6-dev libpng-dev libtiff5-dev libjpeg-dev libharfbuzz-dev libfribidi-dev libfontconfig1-dev libxml2-dev libssl-dev libcurl4-openssl-dev
