That was the same issue I had.  I couldn't dis-entangle all of the
crazy shell stuff he was doing to try to get to the root of the actual
problem.

Had there been something straightforward like:

me@deblive:~$ cd /mnt/whatever
me@deblive:/mnt/whatever$ mkdir foo
me@deblive:/mnt/whatever$ mkdir bar.
Error message here.
me@deblive:/mnt/whatever$ mount | grep whatever
File system and mount options shown here.

then we might have got to the heart of the problem much more easily.
