Bug

What I did

I followed the Phoniebox Development Runbook for Docker environments. I could build all docker images fine but when I start the containers with docker compose -f docker/docker-compose.yml -f docker/docker-compose.linux.yml up both the jukebox containter ends up in a restart loop.

I expected this to happen

The jukebox container should run successfully.

Further information that might help

Possible soluton

I found that that this diff in jukebox.Dockerfile fixed it:

I could create a PR if this solution is accepted.

I just noticed that I get the same error following the official installation docs for future3.

Could fix this with:

sudo pip uninstall pyzmq                                                                                                                                                                                     
sudo apt install libzmq3-dev                                                                                                                                                                                 
sudo pip install -vv --no-binary pyzmq pyzmq --install-option --zmq=/usr

As mentioned by @ChisSoc most likely because of 64bit OS.

Just quick feedback: I ran into the same issue following official future3 guide on pi zero 2w with 32bit bullseye and solved it the same way (only without the sudo)

[abirke]

I am also still seeing this issue on Raspberry Pi Model 3B V1.2, Raspbian GNU/Linux 11 (bullseye) 32-bit, Python 3.9.2, pip 23.1.2, and Commit ID bd7bb789a31d358b505c825c5c695e9c2fc1eace from the future3/main.

The above script seems to still fix the problem although the pip install command options have slightly changed.

pip uninstall pyzmq
apt-get install libzmq3-dev
pip install --no-binary=:all: pyzmq

Should be now fixed on future3/develop
