I've tried to install the MaaS Region Controller via stable ppa on an Ubuntu 14.04lts Svr Edition clear, using the following commands as suggested from official guide
$: sudo apt-get install maas-region-controller
but during the installation of the database I've received the following error:

I've also try to install maas via
$: sudo apt-get install maas maas-dns maas-dhcp
but the error was the same
Why? and is there someone that have tried to install just the Region Controller and a Cluster Controller on a different physical host to create an separate MaaS environment?
Thanks in advance
