[Bug 84201] Re: Right click unmount (umount) of loop device fails

[Daniel Harvey]

Yes, /media/usbdisk is a mounted USB device, and the mount point is a
directory 'fs' within this.

I've done some more checking and I don't believe this is related to the
problem. The problem appears to be related to mount/umount and the use
of loop devices.

My mount line represents the following:

/media/usbdisk/.fs.ext3 --> /dev/loop4 --> /media/usbdisk/fs ext2
file containing EXT3 filesystem --> loop device --> mounted EXT3 filesystem

The problem is that in the past, "umount /dev/loop4" worked, and this is
the command that the Gnome interface is executing.

My setup is as follows:

daniel at elvandar:~$ dpkg -S /bin/umount
diversion by loop-aes-utils from: /bin/umount
diversion by loop-aes-utils to: /bin/umount.orig
mount, loop-aes-utils: /bin/umount

daniel at elvandar:~$ dpkg -l mount loop-aes-utils

||/ Name           Version        Description
+++-==============-==============-============================================
ii  loop-aes-utils 2.12r-11       Tools for mounting and manipulating filesyst
ii  mount          2.12r-11ubuntu Tools for mounting and manipulating filesyst

So, perhaps the problem is loop-aes-utils?
