You must have at least 6GB of free space (Settings > General > iPhone Storage)
You must have a good WiFi connection.
You must have a 50% battery charge and preferably connected to power.
Low Power mode must be turned off.
You cannot be using a VPN.
If you have a beta profile on your iPhone you must remove it.

What do you see on the screen? What makes you believe it is not installing? See this, If your iPhone, iPad, or iPod touch won't update - Apple Support or this, If you can't update or restore your iPhone or iPod touch - Apple Support
