unnormalized quaternions, malformed top_plate.stl and "No map received" when running RVIZ for Clearpath Husky after upgrading to Kinetic

edit

Hello, I have upgraded both the robot-PC and the remote laptop to Kinetic. I have followed the instructions on Husky-bringup tutorials and setup ROS_MASTER_URI and ROS_HOSTNAME on both computers as per instructions. Now once I run roslaunch husky_viz view_robot.launch I get two warnings as listed below:

[ WARN] [1571334225.555070545]: The STL file 'package://husky_description/meshes/top_plate.stl' is malformed. It starts with the word 'solid', indicating that it's an ASCII STL file, but it does not contain the word 'endsolid' so it is either a malformed ASCII STL file or it is actually a binary STL file. Trying to interpret it as a binary STL file instead.

[ WARN] [1571334226.376188060]: Interactive marker 'robot_twist_marker' contains unnormalized quaternions. This warning will only be output once but may be true for others; enable DEBUG messages for ros.rviz.quaternions to see more details.

In addition, I am getting "no map received" on RVIZ when I enable the navigation stack. I would appreciate any help as I am very new to ROS.
