Error message:

roslaunch file contains multiple nodes named [/map_server]. Please check all <node> 'name' attributes to make sure they are unique. Also check that $(anon id) use different ids. The traceback for the exception was written to the log file

Launch file:

<launch>
    <include file ="$(find turtlebot_bringup)/launch/minimal.launch" />
    <arg name="map_file" default="/home/gab/catkin_ws/src/gabS/Desktop.yaml" />
    <node name="map_server" pkg="map_server" type="map_server" args="$(arg map_file)" />
    <include file="$(find turtlebot_navigation)/launch/amcl_demo.launch" />
    <include file="$(find turtlebot_rviz_launchers)/launch/view_navigation.launch" />
</launch>

There's probably another node tag with the name map_server in the launch files you include here. In ROS every node must have unique name tag attribute (as the error message describes). You probably wanted to use only one of the map_server node, therefore delete the remaining ones.
