Not a symbolic link - error while installing ROS (Solved)

I tried installing ROS kinetic based on the instruction given above. Everything seemed to have been installing properly until I got this error:

Setting up ros-kinetic-desktop (1.3.2-0xenial-20180830-145536-0800) ...
Setting up odbcinst (2.3.1-4.1) ...
Processing triggers for libc-bin (2.23-0ubuntu3) ...
/sbin/ldconfig.real: /usr/lib/libnv_extimgdev.so is not a symbolic link

The process just abruptly stopped.

Though most of the functionalities of ROS are still present (I tried running roscore and also turtle_sim) when I tried configuring a joystick for linux (using steps at http://wiki.ros.org/joy/Tutorials/ConfiguringALinuxJoystick) the same error pops up

Setting up joystick (1:1.4.9-1) ...
Setting up ros-kinetic-joy (1.12.0-0xenial-20180826-035200-0800) ...
Processing triggers for libc-bin (2.23-0ubuntu3) ...
/sbin/ldconfig.real: /usr/lib/libnv_extimgdev.so is not a symbolic link

ubuntu@nvidia:~$

I tried connecting my joy stick but it was not detected. Can someone help me out with this error. Thank you.

Dear akashbaskaran,

We’ve posted new PDK and DW on developer.com.
Could you please check if this symptom is reproduced after updating with new PDK and DriveWorks? Thanks.

Hi Steve, I had reflashed Tegra with NVIDIA DRIVE 4.1.8.0 (July 31, 2017) and then installed ROS for it. It worked fine.
