The issue I found after installing DevStack from ./ on Ubuntu 14.04 was with the missing ALLOW_HOSTS entry. The error showed up in the horizon error log, /var/log/apache2/horizon_error.log.

To fix the Internal Server Error 500, edit this file: /opt/stack/horizon/openstack_dashboard/local/

By adding:

ALLOW_HOSTS = [''] # The IP address of your DevStack host machine.

Then restart Apache2:

sudo service apache2 restart
