Updating an iPhone 6 to iOS 16

A. You can't.  The iPhone 6 will only install to iOS 12.5.7. See here: Update your iPhone or iPad Software if you're Experiencing Issues with Location, Date, and Time - Apple Support. And, for the note, even if you could update, only the latest version will install.

So, what to Try:

B. Update Using a Computer:

Have a Computer Handy? If so, try using a computer to update.  Use my User Tip: Update your iPhone Using a Computer - User Tip. If any updates are availabe, they will install, sure enough.

Here is a link that may help - If your iPhone or iPad won't update – Apple Support (UK)

Your tag line says that you have an iPhone 6. That iPhone will never run iOS 13 or later, or offer iOS 13 or later as an update.

To run a newer version of iOS, you

will need a newer iPhone.
