Unable to Build my workspace due to errors in building industrial core (Required for Kuka Arm for Ubuntu 20.04.02-Noetic)?

edit

I followed this link to install kuka_experimental http://wiki.ros.org/kuka_experimental It didn't satisfy all the dependencies and gave this error that industrial_robot_client package was missing.

I installed Industrial Core from source using this link. https://github.com/ros-industrial/ind...

When i ran this:

# checking dependencies
rosdep install --from-paths src --ignore-src

I got an error that a dependency orocos_kdl package is missing.

I installed it from https://github.com/orocos/orocos_kine...

Based on the error i setup a path for the packages to access python2 for building, referring this. https://www.fosslinux.com/39384/switc...

This resolved and build most of the packages but there are some errors that persisted. I have added my error message which i got during catkin build.
