Error with ./build_foxy.sh

[zhichaoliu0921]

Hi I met a error when creating the docker image for ROS 2 Foxy on Ubuntu 20. I was following the tutorial Building ROS 2 Workspaces with Python3.10

My environment information:
OS: Ubuntu 20.04
ROS2 Distributor: Foxy

How to reproduce the error:

git clone https://github.com/NVIDIA-Omniverse/IsaacSim-ros_workspaces.git
cd IsaacSim-ros_workspaces
./build_foxy.sh

Error Print

~/IsaacSim-ros_workspaces$ ./build_foxy.sh
