Comment 2 for bug 2003980

The advised way of dealing with updating images is to upload them with different names. The name of the image needs to be unique, because it's treated as an identifying property of an image, so having two images with different contents but the same name is not something that MAAS expects.

Having said that, it's not clear why the displayed state of image sync appears to be incorrect. This needs to be looked at first before we proceed with fixes.
