Error running heron_world.launch

[djmv]

• OS: Ubuntu 18.04
• ROS Distro: Melodic

• Built from source or installed: Installed by apt

  Expected behaviour I installed heron simulator following instructions in https://www.clearpathrobotics.com/assets/guides/melodic/heron/simulation.html then I tried to run heron_world.launch but said me that teleop.launch not found.

Actual behaviour RLException:` while processing /src/heron_simulator/heron_gazebo/launch/spawn_heron.launch: while processing /opt/ros/melodic/share/heron_control/launch/teleop.launch: Invalid roslaunch XML syntax: [Errno 2] No such file or directory: u'/opt/ros/melodic/share/heron_control/launch/teleop.launch' The traceback for the exception was written to the log file

Other notes Also I installed all teleop packages by apt but the error was not solved. sudo apt install ros-melodic-teleop-* All the packages: ros-melodic-teleop-legged-robots ros-melodic-teleop-tools-msgs ros-melodic-teleop-twist-joy-dbgsym ros-melodic-teleop-tools ros-melodic-teleop-twist-joy ros-melodic-teleop-twist-keyboard

Please try cloning the latest version of https://github.com/heron/heron into your workspace; there was a recent update that added teleop.launch to the heron_control package that may not be available as a .deb yet.

Thanks! @civerachb-cpr I solved the issue. I copied into heron_simulator folder the heron_control folder from https://github.com/heron/heron Then I did catkin_make and relaunch the heron_world and run successfully.
