Worked like a charm few months ago..
I installed a new SSD on my laptop so installed the latest Arduino IDE since than the upload not works.
OS: Ubuntu 19.10
I using an official starter Arduino Uno kit with all of its own cable and parts.
power off/on, cable unplug, board reset not helped...
no cabling on the pins.

avrdude done. Thank you.
Problem uploading to board. See
http://www.arduino.cc/en/Guide/Troubleshooting#upload for suggestions.
This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.
Any Idea?
Thanks!
