Unable to load the SpatiaLite library extension "libspatialite.so.7"

Working with Django and Spatialite? If you updated recently to the last ubuntu version (15.10) and you're getting this error or similar:

Unable to load the SpatiaLite library extension "libspatialite.so.7" because: /usr/lib/x86_64-linux-gnu/libspatialite.so.7: undefined symbol: sqlite3_spatialite_init

You can fix it adding this line to your settings.py file:

SPATIALITE_LIBRARY_PATH = 'mod_spatialite' 

... and installing the package libsqlite3-mod-spatialte

sudo apt-get install libsqlite3-mod-spatialite
