** Bug watch added: github.com/storaged-project/udisks/issues #709 https://github.com/storaged-project/udisks/issues/709 -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to glib2.0 in Ubuntu. https://bugs.launchpad.net/bugs/1852844 Title: Nautilus/Files UI requires sudo access to unmount a disk that can be unmounted successfully without sudo using command line Status in GLib: New Status in glib2.0 package in Ubuntu: Triaged Bug description: An external disk device is declared in '/etc/fstab' with 'auto,nofail,users' options: UUID=aa083302-...-b66c0715eaf1 /media/ushakov/TOSHIBA_SYSTEM ext4 nodev,nosuid,auto,nofail,users 0 2 It is then successfully mounted automatically upon being connected. It can further be unmounted successfully without `sudo` from command line, e.g.: `umount $mount_point`. Meanwhile an attempt to unmount this device from Nautilus/Files UI results in an "Authentication Required" message: "Authentication is required to unmount External USB3.0 (/dev/sdc3) mounted by another user". The expected Nautilus/Files UI behavior would be that the disk device is unmounted silently or just with an non-intrusive notification upon a click on the "Unmount" button near the device label.
