Hello. I have installed NAV on Ubuntu 14.04 using this manual: https://nav.uninett.no/wiki/nav_on_debian But when I try to connect to server with my browser, I receive "500 Internal Server Error". This is what I see in apache's error.log:

What is wrong with my installation?
Hi there,
Ubuntu 14.04 provides Django 1.6; NAV has not been tested on anything newer than Django 1.4. This errors appears to be due to one of many changes between Django 1.4 and 1.6.
The nav Debian package itself is probably wrong to assert the dependency to 'python-django >= 1.4'.
You seem to have three options:
1. Downgrade to Django 1.4 by finding or building a package compatible with Ubuntu 14.04.
2. Forcibly uninstall Django 1.4 and use "pip install 'django>=1.4,<1.5'" to install a compatible version outside of the APT system.
3. Hack /usr/lib/python2.7/dist-packages/nav/django/urls.py by replacing
from django.conf.urls.defaults import patterns, include, url
with
from django.conf.urls import patterns, include, url
and then pray everything will otherwise work fine on Django 1.6. There is a high chance, however, that there will be further errors.
We are generally tracking Debian stable for development dependencies, with a few exceptions, which we are packaging ourselves. Debian are planning to freeze their next stable release around the 5th of November, which means we may start looking at making NAV work with whatever version of Django they freeze on around that time.
