Ошибка при попытке запустить juju bootstrap

Я следовал общим инструкциям по установке MAAS и после того, как мои узлы были успешно созданы, я пошел дальше, чтобы установить juju, чтобы упростить установку openstack, но затем я получил следующую ошибку:

 root@mymaas:/home/user# juju status 2013-02-18 19:52:46,361 INFO Connecting to environment...

Я не знаю, где я ошибся в установке juju, но ниже приведено то, что у меня есть в моем файле конфигурации среды.

juju: environments 
  environments:
    maas:
     type: maas
     maas-server: 'http://{my-ip-address}/MAAS'
     maas-oauth: '${DXSKFbuHn3URhbCdD6:Z9V47vmsS2jDbxL4L2:6dQarDXcGuTZ7nvYemHMAnt2yHnUBRr2}'
     admin-secret: 'nothing'
     default-series: precise

Пожалуйста, помогите!
