Do you use a cable or dock by someother than Apple?

Yes tell us how you are trying to install. What hardware/computer are you using.

FWIW - is your iPad on iOS 11?

I keep getting this message on both my iPad and iPhone, since upgrading both to iOS 11, when plugging the Lightning cable into an Anker USB3.0 hub which - of course - used to work perfectly well under iOS10.

I have now had to plug the Lightning cable directly into my MacBook (via the Apple dongle) which means I have to disconnect the Anker hub (and that means I cannot connect my USB HDD that I use for Time Machine) whilst I connect the iPhone or iPad to the MacBook).

Thankfully I do not have to do that much, other than to transfer music via iTunes (yes, there's some of us who prefer to sync our music we have bought and ripped from CD, rather than have to pay Apple another €10 a month to listen to music we already own...)
