Hi fe7565,

There may have been a temporary issue with the link for the board add-ons. I just tested updating to 1.0.8 in Arduino 1.8.9 and had no problems. If you continue to have the issue downloading the board files, try resetting the json link in your Preferences menu. There may be a syntax error there that is causing the issue.

If you still have issues after retrying and checking the json link for any errors, let us know and we can troubleshoot this issue further.
