Im fairly new to ROS and was trying to go through the ROS2 Tutorial. When Ive reached the "Writing a static broadcaster tutorial" and tried to check for missing dependencies with rosdep install -i --from-path src --rosdistro foxy -y , Ive received the following message:
ERROR: the following packages/stacks could not have their rosdep keys resolved
to system dependencies:
learning_tf2_py: Cannot locate rosdep definition for [tf2_ros_py]
Does anyone know how this problem can be fixed?
(I am using Ubuntu 20.04 and foxy)
Ive already tried to delete the created package and to create a new one but this error keeps coming up nevertheless.
The tutorial provided an incorrect key for tf2. You need to put tf2_ros as dependency in your package.xml instead of tf2_ros_py.
