Docker commands do not respond anymore

Question

Most of docker commands never end. I have to interrupt them manually with CTRL+C. Even simple commands like docker ps or docker info do not respond.

Answer 1

I just had a similar issue as well. Rebooting the server did not work for me. I got this issue, because I just installed a new container with some kind of errors. After that, most Docker commands did not respond. I fixed it by executing the following command:

docker system prune -a

This removes all unused containers. In my case also the container I just added. More information:
