Current Behavior

When I start the docker container, I can see the following logs:

[migrations] started

This renders transmission unusable. I found something on reddit that could (or not) be relevant? https://www.reddit.com/r/Ubuntu/s/6fh1C73eO0

Thanks.

Expected Behavior

No sendto operación not permitted warning and normal transmission start.

Steps To Reproduce

I just downloaded the new docker image. Nothing else has changed.

Environment

- OS:Debian Testing.
- How docker service was installed: from upstream official package.

CPU architecture

x86-64

Docker creation

services:
  gluetun:
    image: qmcgaw/gluetun
    container_name: gluetun
    cap_add:
      - NET_ADMIN
    ports: #make sure to include these for qbittorrent to work
      - 9091:9091       # Transmission UI port
      - 51413:51413     # Torrent port (TCP)
      - 51413:51413/udp # Torrent port (UDP)
      - 8001:8000       # Needed by gethomepage
    environment:
      - SOME STUFF
    volumes:
      - /home/muammar/docker/Gluetun/:/gluetun
      - /home/muammar/docker/GluetunAuth/config.toml:/gluetun/auth/config.toml
    restart: unless-stopped

  transmission:
    image: lscr.io/linuxserver/transmission
    container_name: transmission
    environment:
      - PUID=1000 # User id
      - PGID=1000 # Group id
      - TZ='America/New_York'
    volumes:
      - /home/muammar/docker/Transmission:/config # Change this to your docker config folder
      - /home/muammar/Media:/downloads # Change this to your download folder
    network_mode: service:gluetun
    restart: unless-stopped # This makes sure that the application restarts when it crashes

Thanks for opening your first issue here! Be sure to follow the relevant issue templates, or risk having this issue marked as invalid.

[muammar]

I found a solution. It turns out the issue was gluetun. I had to follow what's stated here:

qdm12/gluetun#700 (comment)

  devices:
    - /dev/net/tun:/dev/net/tun

That made gluetun to start correctly and transmission to run normally.

Sorry for the noise and thank you for your hard work!
