Install Problem - fresh install

[MightyMirko]

Hello

Description

ROS Distro: Galactic
OS Version: e.g. Ubuntu 20.04

Steps to reproduce

cd ~/ros2_ws
git clone https://github.com/ICube-Robotics/iiwa_ros2.git src/iiwa_ros2
rosdep install --ignore-src --from-paths . -y -r
colcon build --cmake-args -DCMAKE_BUILD_TYPE=Release --symlink-install
source install/setup.bash

Expected Behaviour:

Install without fail:

I also had to install ros-control manually. I'd like to contribute but have to dig deeper in dependencies to be sure

I had done things wrong with ros2-controllers .. it was also in my workspace which should not have been there

hi, did you download and source the ros2_control_demos package which is a dependency here ?
Also, make sure you use the galactic branch of the repository as the main branch was ported to humble.
