As best I can tell, the issue is because in /plantsaver/Dockerfile.template --install-options is used on line 15 and forces pip to use setuptools’s install command, which is deprecated.

I believe the problem is rooted in the deprecated Adafruit_DHT library. It relies on setuptools to install dependencies.
The best solution appears to be using the current adafruit-circuitpython-dht library instead
