ubuntu - /var/run/docker.sock: no such file or directory. Are you trying to connect to a TLS-enabled daemon without TLS?

Question

I am very new to the docker when try to run docker info it gives me following error.

$ docker info
FATA[0000] Get http:///var/run/docker.sock/v1.17/info: dial unix /var/run/docker.sock: no such file or directory. Are you trying to connect to a TLS-enabled daemon without TLS? 

I am using ubuntu 14.04. I followed the installation istructions mentioned on https://docs.docker.com/installation/ubuntulinux/#installing-docker-on-ubuntu

But I'm still getting the error. How can I fix this?

Answer 1

This error occurred because I didn't restart my computer after installing docker. Now the above command is working for me.
