Here is how to update your iPhone:

Update your iPhone or iPad - Apple Support

if you have an add-on VPN client app, or add-on security app, remove it, restart, connect to Wi-Fi, and try again.

You’ll be offered iOS 16.2, or maybe iOS 15.7.2. There is no means to get iOS 15.5.

If that update fails, use a computer to update, as linked in the article.
