This is probably a newbie question.... I am not sure when this
started to happen but when, as a user, I try to unmount a USB drive
via the desktop icon I am told that I am not authorized to perform
that operation. After browsing bugzilla and the forums it looked
like the best way to get past this would be to use sudo. However,
editing the sudoers file always throws up a syntax error. I have
tried various commands based on examples but cannot get any to work.
e.g.
ALL /bin/umount NOPASSWD
%users /bin/umount NOPASSWD
%users localhost=/bin/umount NOPASSWD
What is the correct recipe? RTFM only makes my old brain spin.

try :
%users ALL=/bin/umount NOPASSWD: ALL
or maybe :
%users ALL=/bin/umount device NOPASSWD: ALL
where "device" is whatever the usb drive is mounted as.
Not workable if "device" is variable.
Alternately, you could do :
su
(enter password)
umount ...
As to why you are having the problem :
It means that the drive was mounted with root privileges, or the
privileges of another user.
Thus it is requiring root privileges (or that of the other user) to
unmount.
Was it plugged it when the system was booted ? That could cause it to
have root privileges.
Is it in a line the /etc/fstab file ?
(if so, you just have to add the option "users" in the
comma-separated list in the third position in the line.)
Or it could be a bug.
A bug seems doubtful because there do not seem to be any other reports
of this behaviour. I have been forced to take the direct su/password
route.
The medium was plugged in at boot time but has been removed and
replugged a few times. I had not considered that point. What you are
saying is that removable media are treated as fixed if already plugged
in at boot time? This is starting to make sense.
It has happened to me in the past, although currently I have no problem
with a dvd that I sometimes have inserted on boot. (I use Gnome as
well, but haven't yet updated to mga2.)
If that is the cause, either something is not configured right or not
installed, or it is a bug.
If you have systemd activated, a configuration problem is not unlikely.
Will investigate fstab, edit if necessary and reboot without the
drive . And if that works, mend sudoers.
For fstab, the "users" option lets any user unmount the drive, even if
they didn't mount it. As well as mount it. It is a good option to use
for removable media.
Thanks
