Hello,

I used the command as given in the tutorials: roslaunch beginner_tutorials turtlemimic.launch.

On running it, I am receiving the following error:

Traceback (most recent call last):
  File "/opt/ros/jade/lib/python2.7/dist-packages/roslaunch/__init__.py", line 225, in main
    args = rlutil.resolve_launch_arguments(args)

    raise InvalidPackage('The manifest must contain exactly one "%s" tags' % tagname)
InvalidPackage: Invalid package manifest "/home/shobhit/catkin_ws/src/beginner_tutorials/package.xml": The manifest must contain exactly one "description" tags

I have also run the source package. Please help!

As the last lines said, did you check package.xml in beginner_tutorials ? (if the description tag is correctly written)
