You should install ros2_control, you have two options:

• Install sources from this repository or
• sudo apt-get install ros-foxy-ros2-control

ros2_control is not released yet in Galatic, if you are using this version you must install ros2_control from sources.

Please ask this kind of question here: https://answers.gazebosim.org/questions/

Thank you @ahcorde

Not sure if this a local or global issue, but for Foxy, I had to directly git clone https://github.com/ros-controls/ros2_control.git

because my apt-get is fully updated after successfully installing moveit2
but sudo apt-get install ros-foxy-ros2-control gave this error:

not sure if relevant but, I am not using amd64 seen above

processor : x86_64

RMW MIDDLEWARE
middleware name : rmw_fastrtps_cpp

ROS 2 INFORMATION
distribution name : foxy
distribution type : ros2
distribution status : active
release platforms : {'ubuntu': ['focal']}

Would be great to understand why the elegant "debian" install via sudo apt-get install ros-foxy-ros2-control failed.

same error after updating ROS2 key:
curl http://repo.ros2.org/repos.key | sudo apt-key add -

hi @ahcorde
ros2_control is built and sourced,
but gazebo_ros2_control fails to build with same error:

CMake Error at CMakeLists.txt:6 (find_package):
  By not providing "Findcontroller_manager.cmake"

How to solve?
Thank you for your help

[ahcorde]

Can you clarify your setup ?

• ROS 2 version
• packages inside the workspace

[newcanopies]

finally solved -- with a master COLCON workspace for all ROS2 packages:
(this prompted my other Issue question)

export COLCON_WS=~/ws_ROS2
mkdir -p $COLCON_WS/src
cd $COLCON_WS/src
git clone some-ros-pkg-repo
cd $COLCON_WS/
colcon build --symlink-install --packages-select

the below original workspace tree was failing to build inside gazebo-ros2-control/:

~/ws_ROS2/
|__gazebo_ros2_control/src
|__gazebo_ros_pkgs/src
|__ros2_control/src
|__etc/src

Thanks very much again!
