Feisty/Gnome: unmounting volumes on the desktop doesn't work

[Hoffmann]

Since Feisty, Herd 5 (probably since Herd 4, but I can't remember), unmounting ANY volume on the desktop gives me the following error:

"/dev/your-favourite-volume-here mount disagrees with the fstab".

As I found out, this is exactly the same error message when trying to unmount in a shell as non-root user. So, the error message should state something like " Only root wants to mount...". For the desktop it looks like a permission problem? Perhaps udev/hal? I'm using gnome as wm.

I just installed and I am having the exact same issue. I am using the Feisty beta with the current build.

As far as I can see, this happens _only_ with fixed media. Removable media like cd-roms, dvd, usb sticks etc. can be unmounted with no problems. But it would be nice to be able to unmount some partitions as well.

This is the fix. I have been using it for a while, its fine. Though I am running linux the problem is the same. There is one function missing and the function in its place is the wrong one. This bug only affects drives that have an entry in the fstab that starts with "uuid=". The attached patch should be applied to the src-dep of util-linux. I'm not sure but I think that thats even the same for herd. For those of you who want this fix now follow these instructions:

Modify your source.list so you have so the dep-src for the main repository enabled and copy the patch into /tmp. Then run the following commands:

$ sudo apt-get update
$ sudo apt-get install build-essential
$ sudo apt-get build-dep mount
$ cd /tmp
$ apt-get source mount
$ cd util-linux-2.12r
$ ./debian/rules patch
$ patch -Np1 -i ../util-linux_user_mount.patch
$ ./configure
$ make lib
$ make -C mount
$ sudo chown root:root mount/umount
$ sudo chmod 4755 mount/umount
$ sudo mv mount/umount /bin

now you should be able to unmount you drive that was user mounted using a uuid.

sry for some reason I was under the impression we were talking about herd the kernel.... Anyway patch is the same. :-)

This bug is still in Ubuntu Server 8.04. Any chance this patch can get into the distribution?
