Calamari not working Ubuntu 16.04

Hi,

I Installed a functional CEPH cluster under ubuntu 16.04. Now I'm trying to install calamari, but after severals attemps I'm not successful.

After fix all the dependencies and installa calamari-server on my ceph-admin, I get the next error when I try to run #root@ceph-admin:~# calamari-ctl initialize

`Traceback (most recent call last):

Could someone give me some idea? It's a bad idea use ubuntu 16.04 for calamari? I Should use redhat or older 14.04LTS ubuntu?

Start with the reported /usr/bin/calamari-ctl entry point and cthulhu/calamari_ctl.py, then reproduce `calamari-ctl initialize` in the stated Python 2.7 environment. Trace the Alembic and SQLAlchemy imports and compare the dependency and Ubuntu 16.04 setup with the project's supported installation guidance; done means the compatibility cause and supported platform are established.
