if you installed one of the calendar patches or used the develop branch and intend to upgrade MANUALLY, YOU have to get back to the master branch ahead of time check the current branch cd ~/MagicMirror git branch output example * _fix_clipping develop master and if the highlighted (*) name is NOT master then rm package-lock.json rm package.json git checkout master use git branch to verify master is selected before continuing then do the commands as listed in the documentation if you are using my upgrade script, it will handle all this for you.

this release requires a new version of nodejs, which is NOT available on the armv6l processor systems, raspberry pi 0w the install and upgrade scripts will abort manual install last step will fail nodejs test, but new code will be downloaded to reverse the code download do git checkout -b oldbranch tags/v2.30 # npm install not required if on this prior branch hardware upgrade required!!!

we have seen and verified that electron 8.5 and above are not working on raspian Jessie but Jessie is pretty old… u will see an error on npm start (after a version upgrade) /home/pi/MagicMirror__RL1/node_modules/electron/dist/electron: /lib/arm-linux-gnueabihf/libdbus-1.so.3: no version information available (required by /home/pi/MagicMirror__RL1/node_modules/electron/dist/electron) strongly recommended to rebuild a new sd card with raspian Buster
