I installed ROS (jade) and tried navigate and gazebo WORLD. Both were working fine. Then, somehow I had to reinstall ubuntu and reinstalled ROS. Since then, I am facing the problem given below. I installed ROS using link text .

baban@baban-H81M-DS2:~$ sudo apt-get install ros-jade-turtlebot-apps ros-jade-turtlebot-rviz-launchers

Please use the Preformatted Text button for console copy/pastes (the button with 101010 on it). Otherwise it's unreadable.

is it fine now? I have kept the console part separately.

I already did it for you :). My comment was meant for future questions.

Your underlying problem is that you're missing some dependencies. You should make sure that you have turned on universe and multiverse as defined in step 1.1 of the installation:

The other possibility is that you have a conflicting package installed for one of the dependencies.

If you use -o Debug::pkgProblemResolver=yes as an option to apt-get it will give you more information.

I checked the 'universe', restricted and 'multiverse', and all three are enabled. I am still unable to figure out the problem. Last time before I un-installed ROS the tutorial codes were working fine.

This answer doesn't make sense – I thought Gazebo2 (Indigo) and Gazebo5 (Jade) couldn't be installed simultaneously? Tutlebot isn't ported to Jade yet (see @gvdhoorn's answer below) so you can't run the simulation at all

As you can see on wiki/Robots/TurtleBot: "The latest officially supported release is for indigo."

This is confirmed by the ROS Jade Build Status page: none of the turtlebot pkgs have been released for Jade.

I have replaced 'Jade' with 'Indigo' and still the problem persists. I also changed the last line of the .bashrc file as given below.

source /opt/ros/indigo/setup.bash

You'd need to uninstall Gazebo 5 so that you can install Gazebo 2. I'd recommend just uninstalling all of ROS Jade if you're trying to run Turtlebot simulations.
