Latest docker update broke my system

Docker Engine General

So, I was doing some stuff on my NAS, and I saw a few updates in the Openmediavault 7 dash, so I thought let me update this and go on with my day. I did the update, these 3 below:

After this, I started getting tons of emails from watchtower, all like this:
permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock: Get "http://%2Fvar%2Frun%2Fdocker.sock/v1.25/containers/json?filters=%7B%22status%22%3A%7B%22running%22%3Atrue%7D%7D": dial unix /var/run/docker.sock: socket: permission denied

I had to stop it in CLI because I was getting tons of them.

I couldn’t start any of my dockers, still can’t. Except of maybe 3 of them. OMV itself can start, Flame, and notifiarr.

Tried restarting docker, server, nothing worked.

Downgrading Docker to previous version 26.0.1 didn’t help.

I’ve tried to use logic and find anything specific in those few containers that work, anything in their compose files, but nothing special there to make them stand out. I really don’t understand why some work and some don’t.

Here’s for example flame:

services:
  flame:
    image: pawelmalak/flame
    container_name: flame
    volumes:
      - CHANGE_TO_COMPOSE_DATA_PATH/flame:/app/data
      - /var/run/docker.sock:/var/run/docker.sock # optional but required for Docker integration
    ports:
      - 5005:5005
    environment:
      - PASSWORD=hidden
    restart: unless-stopped

I have a dockeruser created, and it’s in the Docker group:

Any ideas?
