Docker hello world not working

I'm trying to start using Docker on my Linux Mint. I'm following the Hello World example, but it doesn't seem to work. Here is my log :

# docker run busybox /bin/echo hello world                                                                                                                                                                                                                     
#

I can type anythin instead of "/bin/echo hello world", but I never get any output (even if the command is invalid).

Any idea what is wrong here ?

Just found the problem : I'm on Linux Mint where cgroup-lite is not installed by default. And when using apt-get install lxc-docker, it is only suggested and not required :

# apt-get install lxc-docker
Lecture des listes de paquets... Fait
Construction de l'arbre des dépendances       
Lecture des informations d'état... Fait
Les paquets supplémentaires suivants seront installés : 
  aufs-tools lxc-docker-0.9.0
Paquets suggérés :
  cgroup-lite
Les NOUVEAUX paquets suivants seront installés :
  aufs-tools lxc-docker lxc-docker-0.9.0

So you have to install it manually.
