GeoNode 2.0 depends on python-dev

After recent ppa update, GeoNode is back on the nightly builds. The problem is now that ​http://geonode seems not to work.

The previous database error is gone

[kalxas]

Looking at the logs, there is no error, layers are updated from GeoServer, all needed packages are installed. I think this is an apache configuration issue.

[kalxas]

After some debugging I found the following:

1. The reason that GeoNode is not working is because the file /usr/lib/python2.7/dist-packages/geonode/wsgi.py is missing.

2. The reason that the above file is missing is because the package python-geonode is removed at some point during the build process. If this is executed on beta3 build, GeoNode will work fine again:

   sudo apt-get install python-geonode
   

3. The reason why python-geonode is removed is because the deb file depends on python-dev, which is removed during cleanup.

The question is: Why is python-dev needed in python-geonode? I believe this is a debian packaging bug.

bugs will always occur - the ability to identify, isolate and fix are keys to moving forward. I have to say I am holding my head in my hands and wondering how to find and fix bugs like this, using a packaging based system, instead of the script based system. Thank you kalxas and also, this makes me concerned for the future of debugging build bugs on the Live.

[kalxas]

Fixed in OSGeoLive PPA. In beta3 try: sudo apt-get update sudo apt-get install python-geonode

GeoNode will be pulled from our PPA now and will not install python-dev.

To be confirmed in next nightly

confirmed fixed in [11160]
