I tried to install the upgrade IOS 15 and it keeps saying can not update at this time try again later. What should I do to get it to update?

Hi,

Sorry to hear you are having issues updating your iPad.

First, confirm you are connected to a stable Wi-Fi network. If so, I would recommend resetting your network settings, reconnecting to the network, and try to complete the update again.

Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings

• If your iPhone, iPad, or iPod touch won’t connect to a Wi-Fi network

If you are still unable to complete the update, place the device in recovery mode to restore to factory settings and l reinstall the latest iOS on a Mac or PC.

• If you can't update or restore your iPhone or iPod touch

This should resolve your issue.

• About iOS 15 Updates
• Set up your iPhone, iPad, or iPod touch
• Restore your iPhone, iPad, or iPod touch from a backup

If your iPad is capable of being updated 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

If you continue to experience difficulties with direct update from iPad Settings, you may have more success if you perform the update using a PC or Mac computer. To do so you will need access to either a PC (with iTunes 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

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.
