  keytool -genkey -v -keystore ~/.android/debug.keystore -storepass android -alias androiddebugkey -keypass android -dname "CN=Android Debug,O=Android,C=US"

# Navigate to your `android` directory inside your React Native app, and re-run `./gradlew signingReport`

This error means you need to add the algorithm to generate the key, I use RSA and this works for me: keytool -genkey -v -keystore ~/.android/debug.keystore -storepass android -alias androiddebugkey -keypass android -dname " CN =Android debugging,O=Android,C=US" -keyalg RSA

It worked, Thank you
