Before you do anything, try to restart your iPhone or iPad to see if this helps.
1. Update servers
Is there anything preventing your device from contacting Apple update servers? There are five things you should check:
- Make sure that your device is connected to the Internet. On your device that you are trying to update, try to visit a website to check if you can access the Internet. Try using a fast Wi-Fi or cellular connection. If your connection is bad, the download may not complete or take too long. If possible, try to use a different Wi-Fi network. If you are having Wi-Fi or cellular connection problems you can see the articles below:
- Visit Apple’s System Status page to see if there’s an outage for the update service.
- If you are using a VPN or a proxy service, they may cause issues. Temporarily try disabling them.
- Apple’s update servers may be too busy or overloaded. This can be the case especially if you are attempting to install a new version of iOS or iPadOS just came out, Because millions of people are trying the same thing at the same time. We recommend waiting for a couple of days before you try the installation again.
- Your device may be too old and thus your device may not be allowed to download the update because your device may not support the latest software versions. For example, an iPhone 6 will not be able to download and run iOS 14.
2. Not enough space
It is possible that your device doesn’t have enough storage space to complete an update. If this is the case, there are two things you can try:
- Go to Settings > General > [Device name] Storage to see how much storage you have. You can make room by removing apps, music, photos, or videos you do not need.
- Or, alternatively, you can update your device via iTunes or Finder. If you want to do this, see that section (#4) below.
3. Manually delete the update and try again
Try removing the downloaded update content and retry again. This will simply restart the update process. Here is how:
- On your iPhone or iPad, go to Settings > General > [iPhone Storage or iPad Storage] Storage.
- You will see your list of apps. In the list, you should see the iOS or iPadOS update. (If you do not see the update, use your computer to update your device, see below).
- Tap the update. Then tap Delete Update.
- After deleting the update, go to, again, Settings > General > Software Update and update your device.
4. Update with iTunes or Finder (Catalina, Big Sur or later)
If you cannot update your device, you can use your computer (PC or Mac). This is very simple. Follow the steps below:
- Connect your iPhone or iPad to your computer with your USB cable.
- In iTunes (if you are using a PC or if you are using a Mac running Mojave or earlier) or in Finder (if your Mac running Catalina or later), select your device.
- Click Check for Update. And then follow the onscreen instructions.
