Hello Laminh,
Welcome to the Apple Support Communities. From your post, it seems there are issues updating your iPad, and we'll do what we can to help.
Try all the steps from here: If your iPhone, iPad or iPod touch won’t update
Also, before trying to delete the update again, restart the iPad: Restart your iPad
Enjoy your day.
There are issues with update of some iPad models to iPadOS 15.0.1/15.0.2. Do you have a WiFi Only, or WiFi+Cellular model of iPad?
For affected WiFi+Cellular models of iPad, many are reporting that removal of the SIM tray from the iPad will allow the verification and installation processes to successfully compete. Other reports suggest that installing a SIM card (whether actove or not) also permits the update process to complete.
You may need to restart the update process, but removing the SIM tray from the iPad is simple and costs nothing to try.
Remove or switch the SIM card in your iPhone - Apple Support
If you have a WiFi Only model, the current workaround is to remove the iPad Passcode - and then re-try the installation process.
Be aware that removing the iPad Passcode has implications for any payment methods registered for ApplePay from iPad - and your Keychain (that includes your saved passwords). Assuming that you have other devices (such as an iPhone), your Keychain will remain preserved in iCloud - and can be easily re-synchronised with your iPad via iCloud. Payment cards registered for ApplePay will need to be manually re-added after the update.
IpadOS 15.0.1
