### Invalid roslaunch XML syntax: [Errno 2] while running a roslaunch launch file

Basically like the title refers on using this command: roslaunch a1_456_referee a1.launch

This is the appearing the error in terminal :

while processing /opt/ros/kinetic/share/turtlebot_navigation/launch/includes/gmapping.launch.xml: Invalid roslaunch XML syntax: [Errno 2] No such file or directory: u'/opt/ros/kinetic/share/turtlebot_navigation/launch/includes/gmapping.launch.xml' The traceback for the exception was written to the log file

Of course I manually looked for the file and found it there in the normal directory, I checked my a1.launch file and my include syntax looks like in order aswel:

include file="$(find turtlebot_navigation)/launch/includes/gmapping.launch.xml" It goes without saying that I am a complete amateur in all this, I've shown some interest in a robotics internship and am required to know basics and all. Thanks in advance!!  2 None jayess 5763 ●20 ●82 ●83 ### Invalid roslaunch XML syntax: [Errno 2] while running a roslaunch launch file Basically like the title refers on using this command: roslaunch a1_456_referee a1.launch a1.launch This is the appearing the error in terminal : while processing /opt/ros/kinetic/share/turtlebot_navigation/launch/includes/gmapping.launch.xml: Invalid roslaunch XML syntax: [Errno 2] No such file or directory: u'/opt/ros/kinetic/share/turtlebot_navigation/launch/includes/gmapping.launch.xml' The traceback for the exception was written to the log file file Of course I manually looked for the file and found it there in the normal directory, I checked my a1.launch file and my include syntax looks like in order aswel: include file="$(find turtlebot_navigation)/launch/includes/gmapping.launch.xml"
