The install as per the instructions (pip3 install .) fails in the dreaded wheel error (online forums are full for various python3 apps) on recent ubuntu versions:
ERROR: Failed building wheel for inkcut
The command suggested for inkut "edge" straight from the inkcut-cutcutgo git works, however:
pip3 install git+https://github.com/virtualabs/inkcut-cutcutgo.git
Enjoy!
