It is installable with pip, so pip must be installed.

To do that, first install pip

sudo apt-get install -y python-setuptools python-dev build-essential

then pull in pip

sudo easy_install pip

next one can install s-tui

pip install s-tui

It's been tried out on raspberry pi, raspian, and on ubuntu 16.04 on intel.

It needs work on armbian, at least on the orangepi zero system.
