Odoo 10.0 Blank Login Screen After Install

After installing Odoo from the rpm and using the nightly repo, I received the following errors.

The following things were checked.
Python packages, those were installed via EPEL.
Postgresql-Server was installed, the odoo user was auto created no additional database work was required.

Sythomthom: Odoo blank login screen.
/var/log/odoo/odoo-server.log traceback messages containing python and execute(self.server.app) .

Solution:
command:npm install -g less
/usr/bin/lessc -> /usr/lib/node_modules/less/bin/lessc

Notes: I prefer to keep selinux enabled, if your still having issues:
seenfore0, test then, setbool for network -P.
I also had to allow firewalld rules for port 8069.
