I use Ubuntu 17.04 64bit. I have this problem with my Canon 120IS. I do not know how to "unmount" using nautilus as no icon appears to unmount. A complete shutdown-restart did not see the camera until I had done this several times. I tried several available usb ports. Funny, when I initiate playback on the camera it does launch Shotwell. It is just that Shotwell does not show the camera.
