[BUG] Canot start on headless machine

[DL6ER]

Is there an existing issue for this?

• I have searched the existing issues

Current Behavior

I cannot connect via browser after starting the container.

Expected Behavior

Be able to connect via browser after starting the container.

Steps To Reproduce

See docker-compose.yml below. With this alone, it does not start on a freshly installed (today!) Ubuntu 24.04.3 LTS server. Besides docker, only btop has been installed and SSH keys have been added to the machine.

Environment

OS: Ubuntu 24.04.3 LTS Server (headless)

$ docker -v

Docker has been installed using the recommended way with the official "convenience script" provided for Ubuntu and seems to be functional, otherwise.

This a bare metal host? VM? Lxc?

[DL6ER]

The host is bare metal Geekom IT13 2025 edition.

[thelamer]

just run docker run --rm -it -p 3001:3001 --shm-size=1gb linuxserver/webtop bash

Did you modify your apparmor config or do any other hardening to this system ?

mknod works on all OSs I have ever tested in Docker.

[DL6ER]

No modifications anywhere except adding SSH keys and installing docker ...

I meanwhile removed docker completely as per their instructions and re-installed it, but, unfortunately, I do get the exact same behavior...

[thelamer]

Try with --security-opt apparmor=unconfined

[DL6ER]

Still exactly the same

[thefaboss]

Hello,
I've got the exact same issue after upgrading docker image to the latest one this evening.

[j0nnymoe]

Hello, I've got the exact same issue after upgrading docker image to the latest one this evening.

If you have the same issue, please post information about your host + how it's deployed to see if we can try and find a common link.

[thefaboss]

Here is my docker-compose file :

services:
  webtop:
    image: lscr.io/linuxserver/webtop:latest
    container_name: webtop
    security_opt:
      - seccomp:unconfined #optional
    environment:
      - PUID=1000
      - PGID=1000
      - TZ=Europe/Paris
      - SUBFOLDER=/ #optional
      - DOCKER_MODS=linuxserver/mods:universal-internationalization
      - LC_ALL=fr_FR.UTF-8
    volumes:
      - ./config:/config
      - /var/run/docker.sock:/var/run/docker.sock #optional
    ports:
      - 3000:3000
    shm_size: "1gb" #optional
    restart: unless-stopped

I've made the upgrade as usual with dockcheck.

When restarting the webtop image, logs show this (like DL6ER) :

s6-rc: warning: unable to start service init-selkies-config: command exited 1

I've rollback to my older webtop docker image and it runs like a charm.

[DL6ER]

Just confirmed that running an older version, e.g.,

docker run --rm -it -p 3001:3001 --shm-size=1gb --security-opt apparmor=unconfined linuxserver/webtop:alpine-i3-dc20b7ca-ls234 bash

works fine!

I still get the same errors, but selkies does not exit with status 1:
