I can’t update this IPad to iOS 16.7.1 and iPadOS 16.7.1

Hi radia225,

Thanks for posting in Apple Support Communities. Since you're having issues with your iPadOS update, we'd recommend starting with the guidance in related article If your iPhone or iPad won't update - Apple Support. The following section may be particularly helpful.

"Remove and download the update again

If you still can't install the latest version of iOS or iPadOS, try downloading the update again:

1. Go to Settings > General > [Device name] Storage.
2. Find the update in the list of apps.
3. Tap the update, then tap Delete Update.
4. Go to Settings > General > Software Update and download the latest update.

If you don't see the update in the list of apps or if the issue happens again, you need to 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

Learn how to use recovery mode if your computer doesn't recognize your device or your screen is stuck on the Apple logo for several minutes without a progress bar."

If the same continues, what exactly happens when you try installing the iPadOS update?

Cheers!
