Hello, I recently started work on an arduino project and downloaded the IDE version 2.2.1. When attempting to upload my code to the Arduino device, I am prompted to install the Arduino AVR boards package. It ends with this error message when I attempt to install the Arduino AVR boards. I don't know what any of this means.
You seem to have a file corruption. It might help to download the IDE again and install it; I'm not sure if you have to clean up first. Alternative can be the solution Could not install Arduino AVR platform: Error: 2 UNKNOWN - #7 by Benjamin269
