Pike - Horizon Internal Server Error

[Haitao Huang]

This is Pike version. Followed Ubuntu related installation guide. Everything else working except Horizon. when access got following error in /var/log/aparche2/error.log

Tried this, did not work:
chown www-data:www-data /usr/lib/python2.7/dist-packages/horizon/utils/secret_key.py

Also tried edit: /etc/openstack-dashboard/local_settings.py with following change and did not work:
TIME_ZONE = "US/Eastern"
or
TIME_ZONE = "America/New_York"
or
LOCAL_PATH = "/tmp"
(right now is LOCAL_PATH = os.path.dirname(os.path.abspath(__file__)))

Both django.wsgi and secret_key.py are root:root

Error message as following:

[Akihiro Motoki (amotoki)]

The error message says "IndentationError: unexpected indent" at local_settings.py", line 393.
You edited local_settings.py and the file contains the indent error in python. This is not a problem of horizon source code.
