A question:
1.
Do you have a MDM profile?
If so, contact your company - IT department.
2.
Have you install / use iOS Beta version?, if so remove the beta profile (Settings -> General -> VPN & Device Management).
Then Restart your iPhone and check for updates again.
If neither applies, see ⤵️
You need about 6 GB device storage and good Service & Wi-Fi.
If they are On, turn Off Hotspot & VPN.
Charge the battery > 70%.
