FP2: Fairphone OS 19.05.3 release

That issue has been reported a couple of times. Do you have an SD card? If yes please use it to retrieve the update log as suggested in this topic:

@Volker

Probably your system partition (or any of the others) is not in original shape (eg by rooting,…). Then OTA update is not possible (only manual). You’ll find more details in recovery when you go to advanced-> copy log-> copying logs to SD card.
