SUMMARY Clicking a LUKS-encrypted device's eject icon in dolphin does nothing and, specifically, does not cryptsetup-close the device as one could expect. STEPS TO REPRODUCE 1. Make a LUKS-encrypted USB stick 2. Plug it in and open it via Dolphin (this will ask the for the password) 3. Click the eject icon 4. Click on the device again OBSERVED RESULT It doesn't ask for the password again (and seems to do nothing at all) EXPECTED RESULT It should ask for the password again SOFTWARE/OS VERSIONS Dolphin 22.04.1 on Fedora f36 ADDITIONAL INFORMATION n/a
Indeed, clicking on the removable device (see also Bug 402690) does nothing, whereas clicking on the unmounted partition instantly remounts it without prompt of any kind. That makes no sense. The pain gets real when you have an external USB enclosure with a couple of LUKS-encrypted disks: not only is there no easy way to lock these, but "safely removing" one of the disks may power off both at once. Granted, the latter doesn't seem to be an issue specific to KDE, but GNOME Disks at least has the courtesy to warn me of the impending blackout.
