   ## Environment details:
   
   Local deployment under ubuntu xenial.
   
   ## Steps to reproduce the issue:
   
   ```bash
   # Equivalent steps in tools/ubuntu-setup/docker-xenial.sh
   sudo -E bash -c 'echo '\''DOCKER_OPTS="-H tcp://0.0.0.0:4243 -H unix:///var/run/docker.sock --storage-driver=aufs"'\'' >> /etc/default/docker'
   sudo gpasswd -a "$(whoami)" docker
   sudo -E bash -c 'echo '\''export DOCKER_HOST="tcp://0.0.0.0:4243"'\'' >> /etc/bash.bashrc'
   sudo service docker restart
   
   docker ps
   ```
   
   ## Provide the expected results and outputs:
   
   Normal `docker ps` output.
   
   ## Provide the actual results and outputs:
   
   ```bash
   Cannot connect to the Docker daemon at tcp://0.0.0.0:4243. Is the docker daemon running?
   ```
   
   ## Additional information you deem important:
   
   I've got fixed under this [solution](https://stackoverflow.com/questions/44678725/cannot-connect-to-the-docker-daemon-at-unix-var-run-docker-sock-is-the-docker).
   
   Therefore, it _might_ need to rewrite some steps in the installation under ubuntu xenial. Related #708 may be required to fix together. Further more, it's better communicate under secure port 2376.
   
   Additional ask, is there any reason to use `aufs` storage-driver instead of `overlay2`?
