Apple has recently launched the iOS 14, and every one of us wants to get our hands on the new iOS.
If you’ve tried to install iOS 14 developer beta version and got an error as “unable to install update and error occurred installing iOS 14” developer beta version. We will see how to resolve this issue in this post.
How to Fix Unable to Update an Error Occurred Installing iOS 14:-
Method 1:-
The first thing you have to do is to find out that you have enough storage to install iOS 14 on your iPhone. Now you have to navigate to the iPhone storage and find so. In this case, I recommend if you have up to 5 GB or 6 GB storage available, then you can get this work well.
Mostly this issue will happen because of the unavailability of enough storage space. To overcome this issue, try to uninstall a few apps and delete large video files and photos.
Make sure you have up to 6 GB available storage to install. If this method doesn’t fix the issue, try out the next method.
Method 2:-
Restart your phone and install or try to uninstall your app store and try to install it again.

Also, try to sign out and sign in again to your Apple Store. Clear all the caches and history from your AppStore and try to install it.
