Build environment: Ubuntu 20.04, Python version: 3.8.10.

[andy31415]

@jczhang: Python 3.10 is needed as a minimum to build. Please update your build environment to meet those requirements.

[andy31415]

You may also need to clean any existing environment just in case (rm PW_ENVIRONMENT_ROOT and/or .environment) so that bootstrap starts fresh.

[jczhang777]

@andy31415 Thank you for your reply. I have successfully compiled the code. However, I have some concerns: Ubuntu 20.04's default Python version is 3.8. What is the purpose of the recent upgrade to Matter's environment components that makes it less compatible with Ubuntu 20.04 LTS? Additionally, I'd like to understand what the upgrade plan is for Matter's Python version going forward.

[andy31415]

We are generally matching https://pigweed.dev/ versioning and they moved to python 3.10. Their intent was to use supported python version however unfortunately they skipped one and we made the team aware of this. In the future the plan would be to only update requirements if python version stops being supported.

For 3.8 in particular, it is already end of life today: https://devguide.python.org/versions/

The only odd bit that we have is that we do not support 3.9 either even though that end of life is 2025.

[andy31415]

Closing as requires python 3.10 or above
