Download the latest release from here. Then install with:

$ dpkg -i python3-pifacecommon_2.0.2-1_all.deb

You may need to reboot.

Or you can install without using your package manager:

$ git clone https://github.com/piface/pifacecommon.git
$ cd pifacecommon/
$ sudo python3 setup.py install
$ sudo bin/post-installation.sh

Replace python3 for python if you're using Python 2.
