ROS2 Foxy: Package 'joy' not found`

[Teknetik]

I am trying to control my home lab robot using a BT Gamepad. I found a library here:

GitHub - Ar-Ray-code/ps_ros2_common: Library for ROS2 that guarantees...

That supports my PS controller.

The problem is no matter what I try I cannot see to install the “joy” pkg?

ubuntu@ubuntu:~/ros2_ws$ sudo apt install -y ros-foxy-joy*

Package 'joy' not found

The problem was:

source /opt/ros/foxy/setup.bash
# I did not source this one

source ~/ros2_foxy/ros2-linux/setup.bash
source ~/ros2_ws/install/setup.bash

Guess I am confused which ones need sourcing when and will have to learn more about this!

Hi @Teknetik , welcome to the community!

I am glad you found the solution to your problem. The reason why you have to source /opt/ros/foxy/setup.bash is because that is where the ROS installation is in your system, and the joy package was installed as a binary (sudo apt install -y ros-foxy-joy*). All packages installed this way end up in that directory.

The other workspaces are created manually, so you would source those when you want to work with packages that you make in them.
