Controller Manager CLI Broken Melodic

[danem]

 rosrun controller_manager controller_manager list

just hangs indefinitely.

rosservice call /robot/controller_manager/list_controllers

works however...

Please provide sufficient details whenever you are reporting an error.
Was it installed or built from source?
Which version of the package or the repo?

[danem]

Sorry for not being more thorough. Here is my environment:

I installed the package via apt with sudo apt-get install ros-melodic-controller-manager. Dpkg and the package.xml file tells me that I have 0.16 installed currently.

I am currently running ros melodic with most everything installed via apt.

We have a test for the CLI and it passes for Melodic. Can it be that you are running this on Python3 perhaps?
I am right now fixing bytes vs strings for Noetic on that but it shouldn't affect Melodic.
Try running controller_manager_scripts from the controller_manager_tests package to verify this.

Sorry for the late response.

I'm running python 2. And sorry, but I was unable to find the controller_manager_scripts you refer to. I've installed ros-melodic-controller-manager-tests.
