RPi.GPIO library using error.

When I try RPi.GPIO example from wiki And code here;

import RPi.GPIO as GPIO
import time

# Pin Definitons:
ledPin = 4

# Pin Setup:
GPIO.setmode(GPIO.BCM)
GPIO.setup(ledPin, GPIO.OUT) # LED pin set as output

print("Here we go! Press CTRL+C to exit")
try:
 while 1:
     GPIO.output(ledPin, GPIO.HIGH)
     time.sleep(0.5)
     GPIO.output(ledPin, GPIO.LOW)
     time.sleep(0.5)
except KeyboardInterrupt: # If CTRL+C is pressed, exit cleanly:
 GPIO.cleanup() # cleanup all GPIO

And I run this command on terminal:

python3 ledblink.py 

I get this error message;

Traceback (most recent call last):
  File "ledblink.py", line 1, in <module>
    import RPi.GPIO as GPIO
  File "/home/rnd/.local/lib/python3.8/site-packages/RPi/GPIO/__init__.py", line 23, in <module>
    from RPi._GPIO import *
RuntimeError: This module can only be run on a Raspberry Pi!

How can i fix that?

Edit1: According to wiki UPBoard supports RPi.GPIO library
