I am using the Orbbec Astra Pro with Ubuntu 18.04 and ROS Melodic. I am using the astra_camera package from GitHub - orbbec/ros_astra_camera: ROS wrapper for Astra camera.
When I run astra.launch I can then run rosrun image_view on /camera/depth/image, but when I try the IR topics or RGB topics I don’t see anything. No error messages either. I have copied the results from running roswtf both on the astra_camera package and from my home directory. I have libuvc installed, so I am unsure if that error is the issue.

Additionally, I have tried the astrapro.launch file, but it fails with the following error:
