Issue

After installing docker on the Windows 10 WSL on Ubuntu. We try to start the docker and pull the docker images. But it shows the following messages

Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?.

Solution

A. Restart docker server from system service

systemctl start docker
gpasswd -a $USER docker

B. Manual start docker service

sudo dockerd

The problem is that docker service doesn’t start. So it will show that message. After you restart the docker service and everything will work!
