Cant open PX4 (waiting for simulator to accept)

I am new to PX4 and ubuntu, I am trying to install PX4 using the guide here: 💻 Setting up your PX4 development environment on Linux — Getting Started with Drone Development - YouTube
Unfortunately I encountered a problem:
After using “make px4_sitl jmavsim” command I am endlessly waiting for the simulator to accept me.

please help !

@daniel319 I think you can already see the error in the log :grinning_face_with_smiling_eyes:

line 62: ant: command not found

Please follow the installation instructions: Ubuntu Development Environment | PX4 User Guide

Thanks! I still have some problems but now i notice the erros, ty!
