Controller Spawner couldn't find the expected controller_manager ROS interface #5

While trying to bring up a Gazebo simulation for my own robot I came across this tutorial. However for both of them I have the same issue:

When running roslaunch urdf_sim_tutorial 13-diffdrive.launch at some point there is

[WARN] [1580815600.480090, 28.275000]: Controller Spawner couldn't find the expected controller_manager ROS interface.

The robot is shown correctly in Gazebo at first, then it retracts the gripper inside its body (which I guess is not intended) and the controls dont work.

It might be a namespace issue according to https://answers.ros.org/question/218373/controller-spawner-couldnt-find-the-expected-controller_manager-ros-interface/

However, I wasnt able to fix it so far (working in ros kinetic). Any ideas?

Ok apparently I was missing required packages. I did something similar to sudo apt-get install ros-kinetic-gazebo-ros-pkgs ros-kinetic-gazebo-ros-control ros-kinetic-ros-controllers and now controlling it kinda seems to work

For future reference, how did you install/clone urdf_sim_tutorial?
