trying to do the project musicfig problem with python-usb

Question

I'm currently trying to do the project made by Dennis Mellican about using a raspberry Pi with the lego dimension platform. He made a step by step guide here https://codeburst.io/my-lego-minifigures-play-spotify-dc397e83280e . I managed to get to the step ./install.sh but i get this error :

(venv) pi@raspberrypi:~/musicfig $ ./install.sh
[INFO] Checking Python version...
[INFO] Retrieve app updates
[INFO] Already up to date.
[INFO] Installing apt-get packages...
E: Unable to locate package python-usb
[ERROR] on line 106

In the github install.sh code available here https://github.com/meltaxa/musicfig/blob/master/install.sh I've found the line in cause here :

sudo apt-get -y -qq install python-usb mpg123

I tried to install either libusb or pyusb manually but I always end with the same message. I'm lost on how to solve this issue. I'm using a raspberry PI 3 model B+ with the os Raspberry PI OS (64 -bit).

Answer 1

ok I found a working solution with bullseye as base instead of bookworm (I use docker so I don't need to mess with the base software of the rpi)

Install jukebox

use bullseye for the rpi as base (rpi imager)

    sudo apt update
    sudo apt upgrade
    sudo apt install apt-transport-https ca-certificates curl gnupg vim
    curl -fsSL https://download.docker.com/linux/debian/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker.gpg
    echo "deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/docker.gpg] https://download.docker.com/linux/debian bullseye stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
    sudo apt update
    sudo apt install docker-ce docker-ce-cli containerd.io docker-buildx-plugin
    sudo usermod -aG docker ${USER}
    sudo reboot

*** create jukebox dir in the pi home folder ***

    mkdir jukebox
    cd jukebox
    mkdir config
    mkdir mp3
    cd config
    curl -L https://raw.githubusercontent.com/meltaxa/musicfig/master/install.sh | bash -s -- --docker
    cd ..

*** edit the config file and replace the path to the mp3 folder

I used /mp3

*** get the bus and device numbers of the lego base ***

    lsusb|grep 0e6f

*** replace "bus" and "device" with the numbers of the previous command ***

    docker run -v /home/pi/jukebox/config:/config -v /home/pi/jukebox/mp3:/mp3 -p 5000:5000 --device=/dev/bus/usb/<bus>/<device> --device=/dev/snd meltaxa/musicfig:latest

*** optional compose file to make life easier ***

create a file named compose.yml with the following content replace the values of the usb device toi the bus and device number found with the above lsusb command

    services:
      jukebox:
        image: meltaxa/musicfig:latest
        ports:
          - 5000:5000
        restart: always
        volumes:
          - ./config:/config
          - ./mp3:/mp3
          - "$HOME/.config/pulse/cookie:/root/.config/pulse/cookie"
          - "${XDG_RUNTIME_DIR}/pulse/native:${XDG_RUNTIME_DIR}/pulse/native"
        environment:
          - PULSE_SERVER=unix:${XDG_RUNTIME_DIR}/pulse/native
        devices:
          - /dev/bus/usb/001/005
          - /dev/snd
        group_add:
          - audio

save it and run it

docker compose up -d

Answer 2

You should NEVER use apt-get use apt (or you may miss vital prompts).

Install python3-usb.

Answer 3

)trying the same thing running into multiple problems install.sh gives also errors with python 3.11.2 which it detects to be a smaller number then the python 3.8.5 required

tried the docker way but that messes up on a rpi4 with bookworm

by the looks of it (date when image was created) python 3.9 was used so way older then bookworm, and the installation instructions, make me think it was originally made for buster (10) with a recompile of the needed python version (3.8.5) in it

if you check apt for python-usb you'll find python3-usb (but that don't work if you change the install.sh file), it will pass by it but does not work

pi@jukebox:~ $ sudo apt search python-usb
