That’s a DNS error. Basically “Try again later” – Might wanna try a new OS install on a new card, and if that don’t work, you’ve got some slightly burned hardware.

lets see if we can work around it. reinstall the exact same version

grep version ~/MagicMirror/node_modules/electron/package.json
mv   ~/MagicMirror/node_modules/electron  ~/MagicMirror/node_modules/electron.save
npm install electron@??? --only=prod  # where ??? is the version number from the 1st statement
