Docker not starting - Python error

[DMan16]

Hello all!
This is my first time using Jellyfin and I decided to go the Docker way (I'm far from an expert when it comes to Docker, but I've dabbled in it for quite some time, so I'm not lost in it).

I did the following steps:

• Pulled the latest Jellyfin DOcker image using "docker pull jellyfin/jellyfin"
  
• Created a new user "jellyfin:docker" with its own folder and permissions "/home/jellyfin" (it has "cache" and "config" folders in it too)
  
• Created a docker-compose.yml in "/home/jellyfin/compose":
  
  Code:

  version: '3.5'
services:
  jellyfin:
    image: jellyfin/jellyfin
    container_name: jellyfin
    user: jellyfin:docker
    network_mode: 'host'
    volumes:
      - /home/jellyfin/config:/config
      - /home/jellyfin/cache:/cache
      - /usr/jellyfin/media:/media
      - /usr/media:/media2:ro
    restart: 'unless-stopped'
• Created the SystemD file for Jellyfin:
  
  Code:

  [Unit]
Description=Jellyfin Media Server
After=network.target docker.service
Requires=docker.service
#
[Service]
User=jellyfin
Group=docker
Type=oneshot
RemainAfterExit=yes
WorkingDirectory=/home/jellyfin/compose
ExecStart=docker-compose up -d
ExecStop=docker-compose down
TimeoutStartSec=4
#
[Install]
WantedBy=multi-user.target
• Reloaded SystemD + the entire system (just in case)
  

When I start the Jellyfin service I get the following error:

Code:

Does anyone know how to solve this?
Thanks in advance for any help!

P.S: Ubuntu server 24.04, Docker version: 27.0.3, Docker compose version: 1.29.2.

You shouldn't need to configure a Jellyfin service. As long as the docker service is running, since you have "unless-stopped" in the compose the docker service will automatically start the Jellyfin container on boot.

Alright, I just went to the folder where the docker-compose.yml is located and ran "docker-compose up -d" - still got the same result as before.

Just noticed your docker compose version. That is waaaay old. 2.28.1 is the latest version. 1.29.2 is three years old.

This is likely a some python or docker incompatibility with such an old compose plugin version.

Update to the latest version and try again.
