“I cannot update my iPhone to the new iOS. There was this error message that said: Apple Software update error occurred while installing update. How can I fix this problem?”

Just when you thought you can now experience the latest iOS features, there was an error occurred and the update wasn’t installed. This can be so frustrating especially if you have been anticipating the said version. There can be many reasons why your iOS software update failed. Sometimes an error code appears that will inform you of the exact issue your device is experiencing and sometimes it can be via Over the Air update failure. It can also be caused by the certain iOS versions like iOS 10.3 or the new iOS 11 bugs. In this article, we will discuss the reasons why some people receive “Apple software update error occurred while installing update” and what are the safest ways to fix this issue. This can be applicable to the iOS versions 10.3 to iOS 11 fixes.

Part 1. Understanding the Error Message (Error Assessment)

If you receive the OTA (Over the Air) update and you followed the instructions on how to do so but you received an error message then try to assess first what could have been the cause of this. Apple software update error occurred while installing update can be caused by many possible reasons which can be any of the following below:

  • No enough space to accommodate the software
  • The update was interrupted
  • Unable to reach Apple’s servers
  • Network strength too weak to complete

Remember that the software update can at least take 2GB of space on the device so before you attempt to do so, make sure you have enough space allotted for the iOS update. Better to take backups of all the contents and then remove all the unnecessary files on the device to give some space. If in case you don’t really have enough space for the new update then try updating the iPhone via iTunes.

Make sure you also have excellent internet connection upon downloading and installing the new update especially for the OTAs. You will receive any of the following messages: "Unable to Check for Update. An error occurred checking for a software update and "Unable to Verify Update. IOS failed verification because you are no longer connected to the Internet." This is why it is highly recommended that you perform any updates via Wi-Fi and on excellent locations to allow maximum download speed.

Whenever updating via OTA (Over the Air), plug your device to a power source or must have at least more than 50% battery life to fully support the entire update process. Lesser battery life will interrupt the download and can cause delay or incomplete download.

In case you experience any of the above errors, then remove and re-download the iOS again.

  • Go to Settings > Tap General > Tap iPhone Storage
  • Find the latest iOS update in the list of apps
  • Tap the iOS update, then tap Delete Update
  • Go to Settings > Tap General > Tap Software Update and download the latest iOS update
