I’ve gotten it working a Pine Rock64 (arm64 also).
Downloaded electron-v1.7.5-linux-arm64.zip listed under electron’s PR
One thing to note: when downloading from the link, the site’s cert has expired.
// Since the cert for the site has expired (but is safe) wget --no-check-certificate https://www.hamidx9.ir/dl/electron_arm64/electron-v1.7.5-linux-arm64.zip // Important make sure to unzip to your electron path unzip electron-v1.7.5-linux-arm64.zip ~/MagicMirror/node_modules/electron/dist/
Once done just started as usual (npm start).
