First thing I see is your trying to install it in a way that is not tested. Only installing the .deb with gdebi is tested. Make sure you have the latest deb file.

Hello JohnT

I am not good in python but when looking at the "c7i96.py" file line 307 it seems compare to other line that setText is waiting for a string ?
Does the letter "f" behind the '{fpm} IPM' normal?

And same question tor the file "card-broken.py", line 10 ?
the letter "f" at the beginning of the command ?

This is line 307 in c7i96.py

		if text:

line 317 in c7i96.py is

			self.maxVelocityLbl.setText(f'{fpm} IPM')

A formatted string starts with the letter f or F then a single or double quote and inside the curly brackets is any code that should be evaluated.

The card-broken.py file is not even used and not even there any more. Perhaps you need a fresh copy of the deb and using the instructions install it with gdebi.

Quite possible that you are tying to use python 2 and install with setup.py which will not work at all.

Your python version is too old... you need a minimum of Python 3.6 for f strings to work. This was introduced 6 years ago in 2015.

www.python.org/dev/peps/pep-0498/

What OS are you trying to install it on?
