I plugged in my iPhone 5 with iOS 10 and saw iPhone in the file explorer. I clicked on the iPhone 'drive' but it was blank. There was a button for ShotWell and I clicked on that. Another 'folder' for iPhone was there too, but when I clicked on it, it said 'Importing, please wait...' and didn't do anything.
Ubuntu 16.04, iPhone 5, iOS 10.1.1
