The problem

I cloned the repo on a Raspberry Pi 4 and followed the instructions to build with Docker but I am unable to run the built image.

git clone https://github.com/openairplay/airplay2-receiver.git
cd airplay2-receiver
docker build -f docker/Dockerfile -t ap2-receiver .

I'm using a CM4 with builtin eMMC.

What commit exhibits the issue?

With which python3 version do you run Receiver?

3.7.3

OS the receiver runs on

Raspberry Pi OS (bookworm, 64-bit)

OS the sender runs

Which sender client was used

No response

Command invocation

docker run -it --rm --device /dev/snd --net host --volume pwd/pairings/:/airplay2/pairings/ --env AP2IFACE=eth0 ap2-receiver

At a guess, it looks like the available Crypto Cipher libs don't have ChaCha. Is a newer Python available? These wheels must be compilable on the target platform in order to support the suites necessary.

You would do well to ask at https://github.com/Legrandin/pycryptodome

pycryptodome in requirements.txt is not version anchored, so this is not an AP2 problem, but a platform/wheel problem, I think.
