Following instructions from: http://emanual.robotis.com/docs/en/platform/turtlebot3/ros2/ For installing ROS2 for Turtlebot3. Turtlebot3 is running Raspbian Stretch with Desktop 4.19.

Error pops up after instructions:

$ cd tb3_sbc_settings
$ ./install.sh

Unable to debug the installation issue of Micro-XRCE-DDS-Agent.
Tried installing the agent package standalone to no avail. MicroXRCEAgent doesn't start the lidar etc services after the ./run.sh command.

Error message after ./install.sh mentioned below. Any leads on how to get the system to build and MicroXRCE activate will be appreciated.
