Jetbot Rebuild Problems

[alanjpritchard]

Hi,
I have been trying to rebuild the jetbot container as I need to modify robot.py to control my stepper motors.
I have tried a number of sdcard versions with not much luck. I have had a number of errors that I have found fixes to but Im still not there. I am getting the error below:

Updating cache with response from “https://files.pythonhosted.org/packages/6c/be/4e32d02bf08b8f76bf6e59f2a531690c1e4264530404501f3489ca975d9a/protobuf-4.21.0-py2.py3-none-any.whl”
Caching due to etag
Cleaning up…

protobuf requires Python ‘>=3.7’ but the running Python is 3.6.9
Exception information:
Traceback (most recent call last):
File “/usr/lib/python3/dist-packages/pip/basecommand.py”, line 215, in main
status = self.run(options, args)

I have tried installing python 3.8 and changing the symbolic link as /lib/bin but it doesnt seem to take effect:

My build so far is as follows:

Download jetbot-043_nano-4gb-jp45.zip
Extract to SDCARD (use Gparted to maximise partition size)
git clone [GitHub - NVIDIA-AI-IOT/jetbot: An educational AI robot based on NVIDIA Jetson Nano.](http://github.com/NVIDIA-AI-IOT/jetbot.git) - this seems to fix 32.5.0 issues
cd jetbot
./scripts/configure_jetson.sh
cd docker
source configure.sh
./build.sh

I’m not modifying any source just trying to rebuild at the moment and I get the python version error.
Any help would be really appreciated.

Thanks
