Не могу создать объектив Unity с Ubuntu 14.04

Я хочу создать объектив Unity, я следую этому примеру: http://developer.ubuntu.com/2012/04/how-to-create-a-wikipedia-unity-lens-for-ubuntu/

Я использую:

quickly create unity-lens wikipedia

Когда я пытаюсь:

quickly install 

У меня есть эта ошибка:

morgan@morgan-laptop:~/wikipedia$ sudo quickly install
Traceback (most recent call last):
  File "/usr/share/quickly/templates/unity-lens/install.py", line 62, in <module>
    os.mkdir('/usr/share/unity/lenses/%s' % lens_name)
OSError: [Errno 2] No such file or directory: '/usr/share/unity/lenses/wikipedia'
ERREUR: la commande install a échoué
Annulation

Итак, Я создаю каталог (спасибо: https://bugs.launchpad.net/singlet/+bug/1100114 ):

mkdir /usr/share/unity/lenses

И когда я пытаюсь установить снова:

quickly install 

У меня есть эта ошибка:

Congrats, your new lens has been installed.

Каков новый способ создания объектива Unity?
