Edit: On Ubuntu 18.04, follow directions here to get chafa sources and build 'em:
https://hpjansson.org/chafa/

Edit2: after doing a ./configure and sudo apt install loop as you realize stuff is missing, you'll get all the way through and it will whine about not being able to find the lib. Do ldconfig and it will shut up.

Edit3:

ubuntu
cd ~
mkdir chafa
cd chafa
curl https://hpjansson.org/chafa/releases/chafa-1.4.0.tar.xz --output chafa.tar.xz
tar xf chafa.tar.xz chafa-1.4.0/
cd chafa-1.4.0/
sudo apt install gcc pkg-config libgtk2.0-dev libmagickwand-dev
sudo ldconfig
./configure
make
sudo make install
