avrdude done.  Thank you.



Problem uploading to board.  See https://support.arduino.cc/hc/en-us/sections/360003198300 for suggestions.



This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.

Try another USB cable.

Try another USB port.

Try another Uno.

Adjusting your Arduino-IDE according to this tutorial will show the maximum information of the upload-process that is possible.

The tutorial is also for compiler-errors but it expands the log-file for the upload-process too
