Nov 04, 2013 avrdude: stk500recv: programmer is not responding. I have enabled /dev/ttyUSB0 under menu Tools → Serial Port. I have also selected the correct board (Duemilanove with ATmega328) from the list. Yet, I am not able to resolve the issue. I have searched online as well and none of the other responses for this problem seem to be working for me. Jan 06, 2021 Error: avrdude: stk500recv: programmer is not responding; Error: avrdude: stk500getsync attempt X of 10: not in sync: resp=. Avrdude: stk500getsync.

Need help, cant upload to my Arduino Uno or Mega anymore...
