Well, seems it doesn't work. I get this error when I finished installation and tried running roscore

for iface in netifaces.interfaces():
OSError: [Errno 22] Invalid argument
By tracing the errors above to the file "ros_catkin_ws/install_isolated/lib/python2.7/dist-packages/rosgraph/network.py", the error is in netifaces.interface() , so I tried using the module netifaces on its own for basic use in a python shell and I got the following error:
import netifaces
netifaces.interfaces()
Traceback (most recent call last): File "<stdin>", line 1, in <module> OSError: [Errno 22] Invalid argument
thus I searched for the source of the module and I had to download the source package from: netifaces - Python, and currently i'm checking possible causes of this error. If there is anyone interested in helping, that would be appreciated
