Update problem on RPi 3+

[Ratsea]

I know this is an old thread but I too am having a problem upgrading a version 1.0.0 to 1.2. I want this as well as a version 2, which is fine.
Version 1 is much simpler for 0183 NMEA only streams.

The problem is a PYTHON compatibility problem, as when using the upgrade tool for 1.0 to 1.2, I get  the following below.
Is there any solution?
