Wsl 20.04 Humble rocker installation error

I installed the rocker of the link below.
However, this error occurred.
for what reason

Hi @lee1062005 - You should follow the instructions provided in here: ROS & ROS 2 Installation — Omniverse IsaacSim latest documentation

you should be able to use Isaac Sim with ROS in docker as well. Can you try it out? Please make sure to follow the setting of env. variables (FASTRTPS one in particular) What is your current setup like? (In terms of Running Isaac Sim on Linux/Windows and ROS 2 on Linux?Windows/WSL)

Hope this helps!
