Hello Punkint,
We'd like to provide you with some assistance with updating your iPad to iPadOS 17. The following steps should help correct this behavior:
"If the update doesn't complete
If you're installing the update, the progress bar might appear to move slowly. The time an update takes depends on the size of the update and the number of files on your device.
When you're updating over the air, keep your device connected to a power source. If your device runs out of power, connect it to a power source and turn on the device to let the update or restore complete.

Remove and download the update again
If you still can't install the latest version of iOS or iPadOS, try downloading the update again:
- Go to Settings > General > [Device name] Storage.
- Find the update in the list of apps.
- Tap the update, then tap Delete Update.
- 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:
