Updating an iPhone 6 Past iOS 12:

A. You can't.  The iPhone 6 will only install to iOS12. 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: iOS 16.

B. So, what to Try:

B. Update Using a Computer:

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

Opinions vary on how much free space is required for an update......some say 5 GB, others 8 GB or more. I can't tell how much free space the phone has.

When all else falls.....and it has for me, even though everything looked good.....I've still been able to update using a PC or Mac.

See this article.

Update your iPhone or iPad - Apple Support

Good Wi-Fi connection? (You cannot use hotspot to update)

Good cellular connection?

Fully charged battery?

Phone battery not on Low Power Mode?

Plenty of free space on the phone?
