i can’t able to install the new version

Make sure that your iPhone is setup to meet the following requirements before you attempt to update the iOS version-

• Your iPhone must have a fast Wi-Fi connection; you cannot update over cellular data or a cellular hotspot
• The iPhone can not be in Low Power mode
• The battery state of charge must be above 50%
• Your iPhone must have at least 6GB or more free storage space
• Your iPhone cannot be connected through VPN
• If you are not planning for it to update automatically you should turn this option off, as it will only update when the phone is plugged in, connected to Wi-Fi and locked
• You should leave the phone plugged in until it finishes updating, both to assure that it remains above 50% and to keep Wi-Fi enabled (Wi-Fi turns off when the phone sleeps if not connected to power).

You are attempting to update your iPhone by using a Cellular HotSpot. You must be on a Wi-Fi Network for the update to download, verify and finish the update.

Make sure that your iPhone is charged more than 50% and is connected to a Wi-Fi Network and then attempt the update again.

I am also having this issue, any further suggestions?
