PiCar-V servo-install returns FileNotFoundError

Robotic kit for Raspberry Pi
1

I’m setting up the PiCar-V and have gotten to the Servo Configuration section: Configure the Servo to 90 degrees. After rebooting, I followed the instructions to run “picar servo-install” but it’s returning with a FileNotFoundError after several lines. I don’t know what file it’s missing or how to proceed, please help?

Thank you for your patient.Unfortunately, the PiCar-V product has been discontinued for several years. As a result, its software is no longer maintained or updated, and it is not compatible with newer versions of the Raspberry Pi operating system.We sincerely apologize for the inconvenience.

Got it. That sounds like it could still work with an older Raspberry Pi operating system. What was the last operating system version of Raspberry Pi it was compatible with? I have a Raspberry Pi 4B and can find older software to install on it. Thank you.
