When opening the Safari browser you might receive an error message saying that 'Safari cannot be opened while it's being updated.' Unfortunately, there are a few things that could be causing this error message. The first thing you should check is to see if your developer has enabled Safari Content Blockers. If they have, you can disable it through Safari’s settings. Then, if you don’t want to disable it, you can try uninstalling the application by visiting this page on the Apple App Store. Then, restart your device.
How to Avoid the Safari Error Message While Updating
The fix is very simple - simply update your iPhone to the latest iOS version through iTunes on your computer. iTunes will not show you the error message, as it allows you to update your iPhone from iTunes directly without going through the Apple servers.
Always consult your phone’s AppStore for the latest iOS release, or go to iUpdate, a great iPhone application to download updates for all your devices from one place, available for both iPhone and iPad. iUpdate also has an update feature, where you can get the latest iOS update on devices that are not currently connected to the internet, simply by connecting them to your Mac.
How to Force-Quit and Restart Safari While It is Updating
If Safari is crashing while it is updating, the issue is that Safari can’t load the new version of Safari while it is still running. The solution is to force-quit the app and restart it. To force-quit Safari, hold down the Command and Option keys and click on the Safari icon in the Dock. While you are in Safari, you can click “Reset to Default” to force the application into its default state before it takes you back to the application’s home screen.
