I am facing very unusual problems. I have been using ROS-Indigo under Ubuntu 14.04 on my Virtual Machine and ROS-Indgio under Ubuntu 14.04 on my laptop. Surprisingly, I am seeing totally different kinds of errors on all of these machines while I am using the same tutorials.
Coming to the point, I am trying to run PR2 moveit tutorials given [here](http://docs.ros.org/indigo/api/moveit_tutorials/html/doc/ros_visualization/visualization_tutorial.html). On my laptop, I am seeing the following error
PluginlibFactory: The plugin for class 'moveit_rviz_plugin/MotionPlanning' failed to load. Error: According to the loaded plugin descriptions the class moveit_rviz_plugin/MotionPlanning with base class type rviz::Display does not exist.
and the following error
Exception while loading planner 'ompl_interface/OMPLPlanner': According to the loaded plugin descriptions the class ompl_interface/OMPLPlanner with base class type planning_interface::PlannerManager does not exist.
It is really very frustrating. So, I tried to run it on my virtual machine as well. Please help me, how can I handle this. I have been spending a lot of time on it and it is not working.
