Did you find a solution for this issue? I've got the same issue

[phillipsnick]

@mohagedorn yep. Use end of life Python 2

Looks like Unipi have abandoned this project as they have no plans to migrate to Python 3.

Kind of regret buying it to be honest! Pretty expensive paper weight at this point as I can't deploy something which no longer receives security updates into production.
