iPad 16.5 stuck preparing update ...

If the update failed to install, you can delete the failed update package - and then download a fresh copy of the update.

To delete the failed update from your iPad:

Settings > General > iPad Storage

Scroll down the list of Apps until you find the Apple Update, tap, then select Delete Update.

After deleting the update, a forced-restart of the iPad is recommended:

Force restart iPad (models with Face ID or with Touch ID in the top button)

If your iPad doesn’t have the Home button, do the following:

1. Press and quickly release the volume button nearest to the top button.
2. Press and quickly release the volume button farthest from the top button.
3. Press and hold the top button.
4. When the Apple logo appears, release the top button.

After restarting, you can reattempt the update:

Settings > General > Software Update

CORRECTION, I claimed victory too soon.

I deleted the update as instructed, restarted my iPad, and started the update again.

No issues this time, until the last few %, install then failed with the message: "Software Update Failed an error occurred downloading iPadOS 16.5". I was not able to install Update 16.5 even after a few tries.

Thank you

If your iPad is capable of update to a more recent version of iOS/iPadOS than is currently installed, these support pages outline both the available methods by which the update can be performed - and troubleshooting should you experience difficulties:

Update your iPhone, iPad or iPod touch – Apple Support

If you can't update or restore your iPhone, iPad or iPod touch – Apple Support

If your iPhone, iPad or iPod touch won’t update - Apple Support

iOS update and restore errors – Apple Support

Be aware that while an iPad may be capable of update, in some circumstances you may need to use a computer to perform the update. To do so, you will need access to either a Windows PC (with iTunes for Windows installed) or a Mac (with iTunes or Finder - as appropriate for the installed version of macOS). Ensure that your installed version of iTunes has been updated to the most recent version; the essential device drivers are included.

Download and use iTunes for Windows – Apple Support

Update to the latest version of iTunes – Apple Support

Update software on iPhone, iPad or iPod touch in iTunes on PC - Apple Support

If you have a beta profile installed, ensure this has been removed from your iPad - as, otherwise, installation of production software updates may be inhibited. This support page provides the necessary information to remove the beta from your iPad:

How to uninstall iOS beta software - Apple Support

You should note that for your iPad to install an available update, its battery must be charged to at least 50% capacity - and/or be connected to its Power Adapter. Similarly, the iPad can only be updated over a standard WiFi connection - or be updated by a PC or Mac using iTunes or Finder - over a USB connection.

If you continue to experience difficulties, you might be best advised to seek assistance directly from from Apple Support. You can contact the Support Team using the Support link at top-right or bottom-left of this page. Alternatively, you can initiate and manage your support cases using the excellent Apple Support App. If not already installed on your iPad, the App can be downloaded from the App Store:

You might also visit the Genius Bar at your local Apple Store or Apple Authorised Service Provider (AASP) - where the technicians will be able to assist:

After multiple failed attempts, I waited a couple of days, and the update downloaded successfully and was installed without issues.

Maybe servers were overwhelmed with users trying to download the update.

All good now. Running iPad OS 16.5

ISSUE SOLVED

I deleted the update as instructed, restarted my iPad, and started the update again.

It was installed without issues.

Thank you
