I installed turtlebot packages from debs. When I run minimal.launch I get the following error

while processing /opt/ros/groovy/stacks/turtlebot/turtlebot_bringup/launch/includes/_robot.launch:
Invalid <param> tag: Cannot load command parameter [robot_description]: no such command [/opt/ros/groovy/share/xacro/xacro.py '/opt/ros/groovy/stacks/turtlebot/turtlebot_description/robots/kobuki_hexagons_kinect.urdf.xacro']. 

Param xml is <param command="$(arg urdf_file)" name="robot_description"/>

I am getting this error after running ubuntu updates this afternoon. I did not get it before the update. Is anyone else getting the same error ?

Thanks,

Prasanna

I never update Ubuntu. This helps a lot ;-)

@prasanna It works for me the first time I did it... But not this time ! Sorry !

New version of xacro has been released yesterday (now version 1.7.3). Download and test it to see if it solves your problem.

I downloaded a new version of xacro doing : "sudo apt-get update" and then "sudo apt-get install ros-groovy-xacro" and it works fine for me now, even with the roslaunch command.

Guys, I'm sorry to inform you that you need to wait a bit longer for a bug fix. The bug fix in xacro release 1.7.3 only solves the problem of 'rosrun xacro xacro.py ...', but not the roslaunch issue. Follow this ticket for more details: https://github.com/ros/xacro/issues/2

@bit-pirate I installed the new xacro release and now the roslaunch works fine except for the laptop battery warning which I have described here - http://answers.ros.org/question/56704/turtlebot-2-errors/?comment=57279#comment-57279
