Foreword
It is agreed upon that installing maas-region-controller by itself is not correct
maas version : 1.5.2+bzr2282-0ubuntu0.2
When installing the maas-region-controller by itself, the installation hangs after the following python backtrace :
...
verifying database maasdb exists: success.
dbconfig-common: flushing administrative password

ImportError: No module named pexpect
This is caused by a missing depedency on python-pexpect. Installing python-pexpect prior to installing maas-region-controller is a valid workaround
