I'm trying to realize an Ubuntu Enterprise Infrastructure using virtualBox creating all VMs. After I followed this tutorials:

• https://wiki.ubuntu.com/ServerTeam/MAAS
• https://wiki.ubuntu.com/ServerTeam/MAAS/AddNodes

without have issues. When use the following guides:

• https://wiki.ubuntu.com/ServerTeam/MAAS/Juju
• http://marcoceppi.com/2012/05/juju-maas-virtualbox/

my environments.yaml's file is:

environments:
  vb-maas:
    type: maas
    maas-server: 'http://192.168.0.10:80/MAAS'
    maas-oauth: '***ssh_key***'
    admin-secret: 'nothing'
    default-series: 'precise'

but when I run

sudo juju bootstrap

receive this error

2012-06-29 23:55:33,568 INFO Bootstrapping environment 'vb-maas' (origin: distro type: maas)...
