Regarding the problem described here:

Privileged Extension OTA package broken for Android 10 / LineageOS 17.1?

So, I have upgraded my system from LineageOS 16 to 17.1 (Android 9 to 10) and it seems that the Privileged Extension OTA package is no longer working properly. I flashed the package directly aftter the upgrade via ADB sideload. The TWRP log shows that the Privileged Extension has been installed but after booting up the system it is nowhere to be found. Apps have to be installed manually. F-Droid itself is working fine though. The Magisk OTA package installed just fine. Installing the Privileged …

If you are on LOS 17.1, you can use the LOS adb root feature to maually push the files of the OTA zip to their respective location.

1. Activate Developer Settings

2. Enable ADB and ADB Root in Developer Settings

3. Extract the OTA zip files

4. Type these commands from within the extracted folder

   adb root
   adb remount
   adb push F-DroidPrivilegedExtension.apk /system/priv-app/
   adb push permissions_org.fdroid.fdroid.privileged.xml /system/etc/permissions/
   adb push F-Droid.apk /system/app/
   adb push 80-fdroid.sh /system/addon.d/

5. Reboot, go to F-Droid Settings and check if the privileged extension is detected

6. Disable ADB Root and ADB for security reasons

This worked for me on Pixel XL (marlin) with the latest lineage-17.1-20200916 installed, but please tell me if this is a stupid thing to do!

EDIT: This did NOT work on my unofficial LOS17.1 Nexus 6P (angler), seems like a failure of the ADB Root feature.
