Removable media icon stays on the dock after eject.

I wonder if this is because the mount still exists. Please reproduce the bug and while you're still seeing the icon run:

  mount > mounts.txt

and send us the file 'mounts.txt'.

I restarted Ubuntu and the icon disappeared.

1) I put a DVD in the optical drive.
2) Ubuntu detected the DVD and displayed the DVD icon on the dash.
3) I pressed the eject button on the optical drive and the disc was ejected. I pushed in the tray.
4) I opened the terminal and typed the command you suggested.

Confirmed from a 19.10 usb stick on a computer with a CD drive, 'gio mount -o' shows the mount&device are removed and nautilus correctly refresh, the launcher doesn't though

I can reproduce this problem with a USB stick as well. I suggest changing the title to "Removable media icon stays on the dock after eject".

To reproduce, I've inserted my USB stick used to install Ubuntu, automounting it; Two items appeared, one that says "Ubuntu 19.10..." and another saying "casper...", then I ejected it with the command `sudo eject /dev/sdx`. The icon saying "Ubuntu 19.10..." is still there. The other is gone.

Tested on Ubuntu desktop 20.04.1 all up to date on kernel 5.4.0-45-generic

i can reproduce this, after nautilus unmount the cd/dvd icon remains on the dock

I can confirm that this still occurs on 20.10. Is there a workaround to remove the icon from the dash after ejecting?

@Bin, The oem bug describes the issue on the desktop and not launcher, could be the same underlining problem though

I don't think that's true. The original OEM bug also refers to the launcher, not the desktop:

"CD/DVD icon in Dock did not disappear"

@seb128,

 I doubt QA used the wrong name, from the screenshot, it should be in launcher. Thanks!

Confirmed in 21.04.

@Tudor, Alt+F2 r will remove the icon from the launcher until this bug is squashed.

It appears that the icon permanence occurs when I eject using the physical button on the drive as opposed to right-clicking and selecting "Eject" or by running the eject command at the CLI, both of which successfully removed the CD icon.

I noticed this issue due an old game CD with redbook audio. When Ubuntu notices that disc, it actually produces two icons on the launcher, one is an audio CD, the other is the data disc. The Audio CD icon will not eject the disc when you right click and select that option. There appears to be no response. If you use the physical eject button on the drive, the audio CD icon will disappear but the data disc icon remains until a reset of the desktop with Alt+F2 r.

It seems it can't be verified with anything else that isn't a CD/DVD, I tried to emulate it using vmware/virtualbox but no luck so far (at least on 21.10 with GNOME 40).

In the same scenario nautilus updates the icon properly right?
Also, nothing from the journal mentions the dock, right?

@Marco,

 On 20.04, In the same scenario nautilus updates the icon properly right. I attached the screenshot at lp:1929021 . Thanks!
