Updating an iPhone:

A. What to Update:

Update Installed Apps along with the iOS.

B. Determining if an iOS Update will Install:

How to do so...

I. Verify Compatibility:

Identify your iPhone model. The first thing that comes to mind in incompatibility being the culprit. So, confirm the model of your iPhone. If iPhone model is incompatible with iOS15 then it is because you iPhone does not meet the hardware requirements for this iOS version(s).

II. If Compatible...

1. Back Up First:

IMPORTANT: If you have an option to update, however, then be certain you backup your iPhone first. That way, you will have something to restore your iPhone from should anything go wrong with the update

then...

2. Proceed with the Update:

Unfortunately, the iPhone 6 is not compatible with iOS 13 or higher.

That model can be updated to iOS 12.5.6, no further.

Unfortunately, asking the same question repeatedly will not change the answer.
