You have not answered the OpenSceneGraph related question on
StackExchange. Please post the output for:

 ldd /usr/lib/x86_64-linux-gnu/libSFCGAL.so

And:

 dpkg -l | egrep "open(scenegraph|threads)"

You probably have the xenial OSG packages installed instead of those
rebuild with the GDAL packages from UbuntuGIS.

Kind Regards,

Bas
