@Blackmirror can you run your mirror with npm start dev and check for errors in the console?

Okay. here:

MagicMirror will not quit, but it might be a good idea to check why this happened. Maybe no internet connection?

I updated to V2.2.1 on my RPI2: no problem.
Calendar entries work better now.
Thanks for the work!

My suggestion would be to back your modules and your working config.js and delete MM and install the new version… That’s the quickest and easiest way

I had to do a complete reinstall. Used a backed up sd card and the same error kept appearing in the logs. Backed up all my configs and mods. Did a fresh install and all works fine. Could have been one of the modules that gave it an error, I do not know but the calendar works great now.
Thanks

@carltonb Well sometimes things get ‘lost’ or don’t install properly…so at times things can go wrong and cannot be fixed so that was the best answer. Glad you got it working!!

ryck

A quick way to fix this:

cd modules/MMM-Buttons
npm install electron-rebuild
./node_modules/.bin/electron-rebuild

It always worked for me…

@ryck said in Black screen after install update v2.2:

cd modules/MMM-Buttons
npm install electron-rebuild
./node_modules/.bin/electron-rebuild

You are my hero… :)
