P.S. I also did the check with the three patches (sorry I didn't see them before) and got the same error. Just in case it was to do with the 'mass patch' you kindly re-did.

Switch to Python 3.x

Find and require at least Python 3.5 which will allow us to address
some deprecation warnings, most notably about the 'imp' module.
The major version 3.5 was first released in September 2015 and should
be available in all major distributions, including Ubuntu LTS 16.04 and
18.04 as well as CentOS/RHEL 7.x and 8.x.
