I have one workspace in Raspberry Pi with Xubuntu and one in Ubuntu PC. I am running ROS Melodic on both. I am able to access Raspberry Pi through Ubuntu PC using ssh.The roscore is running in Raspberry Pi. My ~/.bashrc file settings are as below (Reference: Here):

Raspberry Pi:
source /opt/ros/melodic/setup.bash 
source ~/catkin_ws/devel_isolated/setup.bash 
export ROS_MASTER_URI=http://192.168.2.111:11311 
export ROS_IP=http://192.168.2.111

Ubuntu PC: 
source /opt/ros/melodic/setup.bash 
source ~/DKOBDR_WS/temp_ws/devel_isolated/setup.bash 
export ROS_MASTER_URI=http://192.168.2.111:11311 
export ROS_IP=http://192.168.2.70

The roscore runs in Raspberry Pi correctly, but I am getting the following output with roslaunch in Raspberry Pi:

shaunak@Xubuntu-RPi:~$ roslaunch mobile_robot_pkg keyboard_teleop.launch

RLException: Unable to contact my own server at [http://http://192.168.2.111:39657/].
This usually means that the network is not configured properly.

A common cause is that the machine cannot ping itself.  Please check
for errors by running:
    ping http

The traceback for the exception was written to the log file

I kindly request for some precise guideline for Network Setup as I have gone through http://wiki.ros.org/ROS/NetworkSetup and http://wiki.ros.org/ROS/Tutorials/MultipleMachines, but can not get much out of them.

@gvdhoorn : Thank you. It's working now.

It is already cloned in my workspace.

@gvdhoorn I am not adding -r. My whole command is : rosdep install -y --from-paths src --ignore-src --rosdistro melodi

I am working on a project that has a Robot with Raspberry Pi controlling it and the data of the Robot's diagnostics is sent by Raspberry Pi to a Desktop PC over Wifi. I am able to establish the communication between Desktop PC and Raspberry Pi over Network by referring this: Running ROS across multiple machines I am already done with the results if both the Raspberry Pi and Desktop PC are having ROS installed. I have a launch file called "view_robot.launch" that invokes the RViz and sets the Robot Parametric Environment. Here is the content of the file:

    <launch>
<arg name="model" />
<!-- Parsing xacro and setting robot_description parameter -->
<param name="robot_description" command="$(find xacro)/xacro.py $(find mobile_robot_description)/urdf/robot_model.xacro" />
<!-- Starting robot state publish which will publish tf -->
<node name="robot_state_publisher" pkg="robot_state_publisher" type="state_publisher" />
<!-- Launch visualization in rviz -->
<node name="rviz" pkg="rviz" type="rviz" args="-d $(find mobile_robot_description)/config/robot.rviz" required="true" /> </launch>

Now I need to remove ROS from Desktop PC, Open RViz in it and connect to my Raspberry Pi's roslaunch server that is not having a unique address. Is it possible? If Yes, then I need some references with which I can implement this.
