Error downloading iOS 16.7

Hi callee33,

If you're receiving an error that you can't update iOS due to storage issues, then attempt to update your iPhone using a computer. If your computer has iTunes, you can plug your iPhone into the computer and open iTunes, select the Summary tab and click Check for Update. Check out that suggestion in the article below:

If your iPhone or iPad won't update - Apple Support

If you can't reach the update server or can't verify the update

If you try to update your device, you might see one of these messages: 

* "Unable to Check for Update. An error occurred while checking for a software update."

* "Install Now. This update requires a network connection to install."

Try updating your device again using the same network. If you still see one of these messages, try updating your device using another network or update your device with your computer:

* Update your device using a Mac with macOS Catalina or later

* Update your device using a Mac with macOS Mojave or earlier, or a Windows PC

If the issue happens again after trying to update with multiple networks, remove the update.

Kind regards.
