If you still can't install the latest version of iOS, try downloading the update again:

Go to Settings > General > [Device name] Storage.

Find the iOS update in the list of apps.

Tap the iOS update, then tap Delete Update.

Go to Settings > General > Software Update and download the latest iOS update.

If you don’t see the update in the list of apps or if the issue happens again, you need to update your device with iTunes.

Try updating iOS after each step.

Try Forget the WiFi network and add again

Try another WiFi network

Toggle sets automatically off and then on

Reset your network settings

Force restart your device

Remove any beta profiles, if applicable

If everything fails: - Use iTunes or Finder (for MacOS Catalina+) to update your device instead of over-the-air
