How to update my iPhone?

Here is how to: Update your iPhone or iPad - Apple Support

and what to do: If your iPhone or iPad won't update - Apple Support

As a guess, you’re probably out of internal storage for the update, which means you can either free up that storage, or can use a Mac or PC ro update as described in the above two links.

If you have an add-on first-few-hops VPN client app installed, remoce it, restart the iPhone, and try again.
