Dear Xibo Community
Yesterday while using ssh i noticed 964 login attempts failed, so I updated the server. Using “sudo yum update”. Well, i think i shouldn’t done that. Now docker seems broken 
[d4dd416@LIMONEDS xibo-docker]$ docker-compose -f cms_custom-ports.yml up -d
ERROR: Couldn't connect to Docker daemon at http+docker://localunixsocket - is it running?
If it's at a non-standard location, specify the URL with the DOCKER_HOST environment variable.
I’m trying to fix this…
I also disabled root user deleting his password, suggested by a friend, and added my user to docker group, but for the moment I don’t have a clue to how to restore xibo.
