I tried to install docker on my ubuntu 14.04. After Installation I had some issues you can read them here: docker installation issue file not found after installation
Installation is done now but when I run docker ps -a I got this error:
Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?
I thought okay no problem I start it. So I ran /etc/init.d/docker start
Nothing changed. What is the issue in this case?
Thanks in advance
UPDATE
Docker lock sais
