I was having the same problem, but I did not need to duplicate that file. You can see the thread here: Uploads keep failing
What worked for me was making sure that I…
- Double-check that my board selected is Board328
- Check that your Programmer is Blinks USBtinyISP
- Try pushing the game again even if the blink is off.
I had to restart my computer, use a different USB port for the cable and restart Arduino to make sure I wasn’t missing anything else. Being new to Arduino in general I forgot to double-check all of those settings when I loaded the example.
