What’s the required storage?
I’m trying to upgrade to iOs 17 and I have 8GB available. The software update notice says it requires at least 6.7GB however, I still cannot download the new iOS due to insufficient storage
iPhone 6s Plus, iOS 15

An iPhone 6s (as listed on your signature) will only run up to iOS 15. (currently 15.8.2)
If you are actually trying to update an iPhone Xs or newer to iOS 17, see if anything here helps:
