Cannot locate rosdep definition for [derived_object_msgs]

[CagriCatik]

I am currently trying to launch the carla_ros_bridge. When I run rosdep update, I get the following error message.

ERROR: the following packages/stacks could not have their rosdep keys resolved
to system dependencies:
carla_ros_bridge: Cannot locate rosdep definition for [derived_object_msgs]
Continuing to install resolvable dependencies...
#All required rosdeps installed successfully

And after ros2 launch carla_ros_bridge carla_ros_bridge.launch.py timeout:=30

Does anyone have any ideas?

I have the same problem as you, and I tried to use carla_0.9.12 and carla_0.9.13, both reported the same error, no module named 'derived_object_msgs'

[CagriCatik]

There is no derived_object_msgs for galactic ...

What is your output after you run the command rosdep install --from-paths src --ignore-src -r? But if you have foxy installed, it should work without any problem.

Thanks a lot,I changed the ros2 version to foxy,then everything went well.I'm sorry that I know nothing about your problems,but you can try this: mkdir -p ~/carla-ros-bridge && cd ~/carla-ros-bridge git clone --recurse-submodules https://github.com/carla-simulator/ros-bridge.git src/ros-bridge source /opt/ros/foxy/setup.bash rosdep update rosdep install --from-paths src --ignore-src -r

mkdir -p ~/carla-ros-bridge && cd ~/carla-ros-bridge git clone --recurse-submodules https://github.com/carla-simulator/ros-bridge.git src/ros-bridge source /opt/ros/foxy/setup.bash rosdep update rosdep install --from-paths src --ignore-src -r

Had the same issue. Resolved it by running the following in my terminal: sudo apt install ros-foxy-derived-object-msgs sudo apt install ros-foxy-ackermann-msgs
