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

Question

Problem: I am trying to run docker inside vagrant, my Vagrantfile contains following:-

  config.vm.provision \"docker\" do |d|
     d.run \"ubuntu\",

I faced a similar issue, running the command sudo service docker restart, followed by restarting the docker image fixed the issue for me
