Hi, I have a problem running docker on Debian 11.
The installation goes fine, but docker does not start.

Try to run journalctl -xe -u docker as root to find more log messages. This is probably what systemd would recommend when you try to start or restart the docker daemon.

I have similar

This means the service could not start because the configuration is wrong or some dependencies are missing. So systemd tries to restart the daemon and reaches the restart limit. I have similar error when my /etc/docker/daemon.json has syntax error or invalid configuration.

I tried the installation process inside an LXD virtual machine. It works perfectly so the reason of the issue must be your environment.
