F-Droid is fully integrated in the official LOS17.1, but Aurora services isn’t. Concerning Aurora I see 2 options for you in the official LOS17.1 after installing it via F-Droid:
- If you chose
fastboot oem lockyour LOS17.1 device, use e.g. the native installation method within Aurora
- If you keep the bootload unlocked, you may download https://github.com/fwg-cag/treble_build_los/raw/lineage-17.1/AuroraServices-v1.0.5-ota.zip and
adb sideload AuroraServices-v1.0.5-ota.zipvia TWRP (donnot forget to mount system first and uncheck ‘unmount system before installing a zip’ in the TWRP settings!). So, Aurora Services will be installed and survive the next LOS17.1 OTA, but you still may update it this way once required.
