I've got mitmproxy installed via both pip (--user) and apt.

[Sanqui]

Please install the mitmproxy and brotli Python modules with pip install mitmproxy brotli (for reference, this is done automatically in the Docker/Podman container)

[TheTechRobo]

As I said, both are already installed.

I can access them through the python3 REPL.

[Sanqui]

Sorry, I missed that. Does your default python --version happen to be Python 2?

[TheTechRobo]

Oops, that's the problem. Sorry, my bad.

[Sanqui]

I'll keep this issue open because Discard2 should try and use Python 3 automatically.
