Apple periodically releases updates for the iPhone, iPad, and iPod touch. Updates for iOS are released via over-the-air software updates. These releases include bug fixes, additional features, and improvements. Thus we recommend installing the latest available updates.

If you see this error when you update your iPhone, iPad, or iPod, here is how to troubleshoot it:

Before continue, it is very important that you make a backup. There are basically two ways to do this:

  • You can use iCloud. On your iPhone or iPad, go to Settings > [your name] > iCloud > iCloud Backup.
  • You can also use your computer, Mac or PC: Connect iPhone or iPad and your computer (Mac or PC) using USB. Open iTunes (if this a PC or if this a Mac running macOS Mojave or earlier) or Finder (if this is a Mac running macOS Catalina).
  • Select your device and click Back Up Now.

  1. I just had this problem and for the longest time version 13.7.1 would not update; it kept giving me the error message and unable to install. It was already downloaded on my phone. I had over 50 gigs of space available. After doing everything on every website I could find, I cut off my VPN (I am using NordVPN) and when I tried again to install, it worked!!!! I don’t understand why there are quite a few services and sites that are not working when my VPN is enabled.
