[rosrun] Couldn't find executable named display_urdf below /opt/ros/kinetic/share/urdfom_py #29

Using ROS Kinetic. urdfdom_py installed via apt-get.

To replicate, $ rosrun urdfdom_py display_urdf or $ rosrun urdfdom_py display_urdf $(rospack find MY_PACKAGE)/urdf/MY_ROBOT.urdf

produces the following message 

[rosrun] Couldn't find executable named display_urdf below /opt/ros/kinetic/share/urdfom_py

Hi @josephcoombe , would you mind posting the output of apt show ros-kinetic-urdfdom-py?

For example this is the output I see.

I'm guessing it has to do with the different line: APT-Manual-Installed: no

Hmm I wouldn't expect that line to cause the difference. Mine says manually installed because I installed it explicitly in a docker image to test this.

What do you see when listing the contents of this folder? ls -lh /opt/ros/kinetic/lib/urdfdom_py

I see

I'm unable to reproduce so far. Here's output I see with a urdf in robot_state_publisher.

$ rosrun urdfdom_py display_urdf $(rospack find robot_state_publisher)/test/one_link.urdf

Got it to work after reinstalling ros-kinetic-desktop-full after which I had to install rosbash again.

Not exactly sure what happened - other than I believe I ran a sudo apt-get autoremove beforehand.
