Method 3. Close Settings App and Wait for Some Time.
If you have retried but nothing works, maybe you can try refreshing your Settings app or just wait for some time rather than rush to the upgrade. To close the Settings App you should: Double tap your Home button > Swipe up on the Settings app until it slides out of view. Next you can try to install the update again: Tap Settings and go to General >Software Update.
Method 4. Turn Off Wi-Fi and Switch to the Cellular Data.
The same problem occurred when users want to upgrade to iOS10.3 beta 1. However, people found out that if they download the beta profile via Wi-Fi, then switch to the cellular data when the Install Now button appears, it would update successfully.
