Not working with Libreelec on RPI4

[Sleipnir-1]

Output of docker inspect jdownloader --format='{{index .Config.Labels.version}}':

2.0.3-armel

Description I installed libreelec 10.0.2 on my Raspberry Pi 4 4GB and wanted to use jdownloader with it. The only possibility is to use docker, but I always get the errors shown below when starting the container.

Docker compose I used to start the container

services:
   jdownloader:
    image: jaymoulin/jdownloader
    container_name: jdownloader2
    restart: always
    user : 0:0
    volumes:
        - /storage/JDownloader2/app/cfg:/opt/JDownloader/app/cfg
        - /media/Seagate\ Expansion\ Dr/Data/Download:/opt/JDownloader/Downloads
        - /storage/JDownloader2/app/logs:/opt/JDownloader/app/logs #optional
        - /etc/localtime:/etc/localtime:ro #optional
    environment: 
            MYJD_USER: ******** #optional (see [Identify](https://github.com/jaymoulin/docker-jdownloader#identify))
            MYJD_PASSWORD: ******** #optional (see [Identify](https://github.com/jaymoulin/docker-jdownloader#identify))
            MYJD_DEVICE_NAME: RPI4 #optional
    ports:
        - 3129:3129 

Steps to reproduce the issue:

1. Enter Docker compose above in portainer, which runs on RPI 4 Libreelec.
2. Error appears.

Describe the results you received:

/opt/JDownloader/daemon.sh: 1: kill: Usage: kill [-s sigspec | -signum | -sigspec] [pid | job]... or
kill -l [exitstatus]
cp: target '/opt/JDownloader/app/libs/' is not a directory
Error: Unable to access jarfile /opt/JDownloader/app/JDownloader.jar

the above looped over and over.

Provide some logs (docker logs jdownloader) see results.

Additionally, I tried with this config and the jdownloader-block.txt to debug with my limited knowledge, but I wasn't able to find the problem.

I don't know if this is related, but RPI4 architecture should be armhf, not armel. Maybe docker for LibrElec doesn't identify correctly or if it's on purpose but you could try with "jaymoulin/jdownloader:2.0.3-armhf" instead

I had the same problem as the OP and this fixed the issue. Thank you!
