INSTALL_FAILED_INVALID_INSTALL_LOCATION

When installing the release to a Linage 14.1 device is get the following error:

Preparing system to install APK …
1. adb shell su root mount -o rw,remount /system
2. adb shell su root chmod 777 /system/lib/
3. adb shell su root mkdir -p /system/priv-app/AppFuzzer
4. adb push ./signed.apk /data/local/tmp/AppFuzzer.apk
[100%] /data/local/tmp/AppFuzzer.apk
5. adb shell su root mv /data/local/tmp/AppFuzzer.apk /system/priv-app/AppFuzzer/AppFuzzer.apk
Installing the app ...
Failure [INSTALL_FAILED_INVALID_INSTALL_LOCATION: Package couldn't be installed in /data/app/com.example.link.appfuzzer-1: Cannot install platform packages to user storage!]

Alternative idea:

1. Create an update zip
2. Install it via recovery automatically

That should allow us to install system apps automatically. @2xlink: Can you test this approach?
