docker.sock. Is the docker daemon running?

Getting the above error while running any docker command. When i run the following command

`$ sudo docker info`
_Output_
`Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?`

**None of the docker commands are working. All of them throws same error.**

`$ sudo systemctl status docker`
_Output._
