[brand000]

hello. l'm having some serious problem getting the px4-offboard example to work. but I was wondering if how to resolve the following error.

os: ubuntu 22.04
ros: humble
python: 3.11

command:

cd ~
mkdir ~/microros_ws
cd microros_ws
git clone -b $ROS_DISTRO https://github.com/micro-ROS/micro_ros_setup.git
mkdir src
mv micro_ros_setup/ src/
colcon build
source install/local_setup.sh

output:
