ubuntu docker.io : docker.sock permission denied issue #163

If you experience this :

$ docker images
2013/08/16 19:05:13 dial unix /var/run/docker.sock: permission denied

Then just use this temporary fix (as suggested here https://github.com/progrium/dokku/issues/163):
 
$ sudo chmod 777 /var/run/docker.sock

and enjoy your containers again

$ docker images
REPOSITORY          TAG                 ID                  CREATED             SIZE

(empty list because I started from scratch again)
