Hey everyone! I recently ran into an issue after updating my computer. I had removed all Docker instances and installed the latest version of docker-ce on my Ubuntu 25.10 system. After that, I set up Portainer and a few other services like Kavita and Audiobookshelf, and started working with Traefik. However, after some downtime, I updated everything, and now it seems like my Docker containers have disappeared. When I check with `docker ps -a`, I don't see any containers, and they aren't showing up in Portainer either. I even removed Docker completely and reinstalled it, but the containers still start up automatically from my `docker-compose.yaml` files. I'm at a loss for what to do next aside from a complete OS reinstall. Any advice would be greatly appreciated!

If your system updates included a new Docker version, that might be causing the issue—especially if it stopped all running containers. Try going to the directory with your `docker-compose.yml` and running `docker compose up -d` to bring them back up. That could fix it!
Make sure you didn't install Docker through Snap. If you did, try purging that version as well as Snap completely. Otherwise, you might just have a conflict there.
Have you tried running `sudo docker ps -a` to see if they show up? Sometimes permission issues can mask containers.
Nope, it still just shows the headers with no containers listed. I think I might have two Docker instances running... I can see some ports being used but not the containers themselves.
It could be a data root issue. Docker usually uses `/var/lib/docker` by default. You can run `docker info` to check which data root it's currently using and ensure you're looking in the right place.

I actually installed it using APT, not Snap.
