There is supposed to be a line above that one, saying what it actually read– the “expected signature” line always follows that if the value is wrong. It should be something like “avrdude: Device signature = 0x1e9514 .
You may need to just scroll up a line to see it.
If you’re doing this from within the Arduino IDE, you may need to turn on verbose mode in the preferences.
