Hello @aaamirrr78 and welcome to the community!

Make sure you have enough space on your internal memory prior to the update. You can move media to your SD card if available, you can also clear cached files by  going to Settings -> Storage -> wait for the software to calculate storage data -> Tap on "Cached data" -> Confirm deletion
