always updating messa

I am consistently receiving an error message when I try to update my iPhone 6. It tells me that I am still updating from a previous update which was months ago when I first purchased the phone.

I am an artist so I have a lot of large image files that clearly are using up too much space. Should I aluminate most of my photographs from iCloud in order for this to function properly.

I was told recently at an AT&T store that I can’t add any additional space so that won’t solve the problem. They suggested just not updating but if I do that I continue to get the annoying messages that interfere with everything else I’m trying to do.
