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.

Udisk upstream fixed it in this commit
https://github.com/storaged-project/udisks/pull/710

Thanks again for upstream the problem and helping driving it to resolution! It should we fixed in the new udisk update (and then maybe we can consider doing a SRU to the LTS)
