Hi, I have recently tried to install NAV on a computer running Ubuntu Linux. Seems like I hav an issue with the Apache/Python configuration, if I try to enter the NAV web interfac (click on index.py) I get this responce:
MOD_PYTHON ERROR

ImportError: No module named nav.web
Have you seen this before/any idea where the problem might be?

Hi Jan,
Which version of NAV is this, and did you install from a package or from source?
It looks like something is wrong with your Apache setup. NAV (unfortunately) requires being accessible directly from the DocumentRoot, often meaning it needs its own virtualhost. Your NAV web interface seems to be installed in /var/www/nav/, while your Apache DocumentRoot is set to /var/www/. You need to set the DocumentRoot to /var/www/nav, or create a virtualhost with this DocumentRoot.
If you were using Morten Werner Forsbring's Debian package, it installs a virtualhost example config file (somewhere in /usr/share/doc/nav, I believe). There's also a wiki page on installing NAV from source on Debian, which might be useful if you're stuck (though most of this is taken care of if you are using the deb package): http://metanav.uninett.no/installing_from_source_on_debian#configuring_apach...
I did install from source, but I have now tried to install the Debian package on a Debian box. It went generally well, but there's one issue....when I click on Netmap I get the following error message:

Doesn't look like Kristian's reply made it onto the list for some reason, although you might have received it privately.
This is a known bug: https://bugs.launchpad.net/nav/+bug/345835
It has been fixed for the upcoming 3.5.3 release. I think it's about time we start releasing it, we already fixed about 15 bugs since 3.5.2, and are contemplating adding a small feature to the release as well.
