debootstrap not installing dapper

[Russell Davie]

Hi All

Running debootstrap stops at installing core packages.

Dapper is to be installed in /dev/hda7.

Command from the terminal:
 sudo debootstrap  --arch i386 dapper /mnt/hda7/ http://archive.ubuntu.com/ubuntu

This downloads the packages and extracts them, however stops at installing:

I: Extracting zlib1g...
I: Installing core packages...
W: Failure trying to run: chroot /mnt/hda7 dpkg --force-depends
--install var/cache/apt/archives/libc6_2.3.6-0ubuntu20_i386.deb

Running the command in chrooted /dev/hda7 fails as well and spews out
stuff like this:

Preparing to replace libc6 2.3.6-0ubuntu20
(using .../libc6_2.3.6-0ubuntu20_i386.deb) ...
/var/lib/dpkg/tmp.ci/preinst: line 126: /dev/null: Permission denied
/var/lib/dpkg/tmp.ci/preinst: line 131: /dev/null: Permission denied

and:
dpkg: libc6: dependency problems, but configuring anyway as you request:
 libc6 depends on locales (>= 2.3.11); however:
  Package locales is not installed.

What is happening here? How can this be fixed?

TIA
