When you 'hover on/move your mouse on' the warning symbol, do you see anything more information?
Do the MM logs show anything just after you failed to upload the image?
As an alternative you could manually upgrade the controller(s), or open a TAC Support case.

Subject: Can't load AOS image for controller on Aruba Conductor 8.10.0.5
Hi all,
I'm facing an issue in that I can't upload an AOS image for the controller on the MM (preparing to upgrade the controllers).

The controller is AOS 8.10.0.2
The MM is AOS 8.10.0.5
It's working properly with my lab MM, but with my production MM It isn't.
Both MMs are the same version.
Anyone else has this problem or knows about it?
Thanks for your reply.
