Docker Can't Connect to Docker Daemon

After I update my Docker version to 0.8.0, I get an error message while entering sudo docker version:

Client version: 0.8.0
Go version (client): go1.2
Git commit (client): cc3a8c8
2014/02/19 12:54:16 Can't connect to docker daemon. Is 'docker -d' running on this host?

And I've followed the instructions and entered command sudo docker -d, and I got this:

[/var/lib/docker|2462000b] +job initserver()
[/var/lib/docker|2462000b.initserver()] Creating server

How do I solve the problem?

  2. Add the user to the docker group.
    sudo usermod -aG docker $(whoami)
  3. Log out and log back in to ensure docker runs with correct permissions.
  4. Start docker.
    sudo service docker start
