Issue
I feel like this is covered territory here, but the issue is has appeared on two separate occasions for me--first when upgrading from Ubuntu 12.04 to 14.04 in May. I got it fixed then, but I recently set up a virtualenv with and that has caused some crossed paths, so to speak. Signs are that python-qgis is installed and that it is a path issue at runtime.
qgis.org says to set my PYTHONPATH=/qgispath/share/qgis/python, and it appears that the package manager used /usr/share/qgis/python on my system.
My issue is that for troubleshooting purposes, I am not certain that is indeed where the python wrapper is located--certainly, using that path doesn't fix it, so I am looking for further troubleshooting tips.
Details below:
When booting qgis 2.4, I get
Couldn't load PyQGIS.
Python support will be disabled.
