I use a USB device with SD-card slots. It works fine, but I cannot seem to unmount it on a proper way from user space.
- Right clicking on the memory stick icon and selecting "eject" does nothing
- Same with "quit" removes the dot and closes the nautilus window, but the SD-card is still mounted accord to "sudo mount | grep /dev/sdc1"
- umount from user space gives error message (as I suppose it should) "Error unmounting block device 8:33: GDBus.Error:org.freedesktop.UDisks2.Error.Failed: Error unmounting /dev/sdc1: not mounted"
- sudo umount /dev/sdc1 works fine
This used to work "before", I don't know exactly when.
I am running Ubuntu 20.04
