Cant install update

Hello NichAhmed,

Thanks for reaching out to Apple Support Communities. We see you have some questions about updating your device, and we'd like to help. To update your iPhone or iPad, you need a compatible device, an internet connection, and enough storage. It also helps to keep your device connected to a power source. This resource has some good suggestions If your iPhone or iPad won't update:

You might be unable to update your iPhone or iPad wirelessly — or over the air — for one of these reasons:

* Your device doesn't support the latest software

* There isn't enough available storage space on your device

* The update takes a long time to download

* Your device isn't able to reach the update server

* The update doesn't complete

Let us know if the steps in that article helps.

Regards.
