Why cant I run roscore on raspberry pi3?

I installed ros indigo with following this website and after sourcing and running roscore it shows:

Traceback (most recent call last):
  File "/opt/ros/indigo/bin/roscore", line 69, in <module>
    import roslaunch
  File "/opt/ros/indigo/lib/python2.7/dist-packages/roslaunch/__init__.py", line 61, in <module>
    from .scriptapi import ROSLaunch
  File "/opt/ros/indigo/lib/python2.7/dist-packages/roslaunch/scriptapi.py", line 42, in <module>
    import roslaunch.parent
  File "/opt/ros/indigo/lib/python2.7/dist-packages/roslaunch/parent.py", line 54, in <module>
    import roslaunch.server
  File "/opt/ros/indigo/lib/python2.7/dist-packages/roslaunch/server.py", line 78, in <module>
    from rosgraph_msgs.msg import Log
ImportError: No module named rosgraph_msgs.msg

P.S i tried reinstalling again but results were the same. Using debian jessie

It looks like your PYTHONPATH isn't set correctly. Did you source the setup.bash or setup.sh for your ROS installation before trying to start roscore?

It would also help to know which OS you're using, whether it's a 32-bit OS or 64-bit, and which instructions you followed to install ROS.
