[Jean-Baptiste Lallement (jibel)]

The deb file itself is not corrupted and can be unpacked/uncompressed manually.

There are the following lines in the log file:
debootstrap: ar: short read
debootstrap: zcat: short read
debootstrap: chroot: can't execute 'mount': no such file or directory

[James Page (james-page)]

Reproduced this on natty-server-i386.iso image - gave up pressing the prompt in the end.

[Colin Watson (cjwatson)]

We need a new base-installer to match the new debootstrap.

This bug was fixed in the package base-installer - 1.116ubuntu1

---------------
base-installer (1.116ubuntu1) natty; urgency=low

  * Resynchronise with Debian (LP: #724822). Remaining changes:
    - Use and depend on the Ubuntu keyring.
    - Enable the restricted component by default, unless
      apt-setup/restricted is preseeded to false.
    - Set up the default sources.list to look in -updates and -security (the
      latter from apt-setup/security_host) as well as the unadorned suite;
      also -proposed if apt-setup/proposed is true.
    - Use Ubuntu kernel image names.
    - Allow preseeding base-installer/kernel/override-image to force a given
      kernel to be used.
    - Install busybox-initramfs rather than busybox.
    - Revert Joey's patch to call base-installer.d hooks after running
      debootstrap, which broke console-setup's expectation of being able to
      insert its configuration file into /target before console-setup is
      installed by debootstrap.
    - Add armel/imx51, armel/dove, and armel/omap subarchitectures.
    - Install kernel headers to match the kernel. This may be overridden by
      setting base-installer/kernel/headers to false.
    - Add base-installer/kernel/backports-modules template, which may be
      preseeded to install selected linux-backports-modules-* packages.
    - Run dpkg with --force-unsafe-io during installation.

base-installer (1.116) unstable; urgency=low

  [ Colin Watson ]
  * Support AMD CPU family 20 (thanks, Keng-Yü Lin; LP: #676838).

  [ Joey Hess ]
  * pkgdetails: Return the value of the field specified by the
    DEBOOTSTRAP_CHECKSUM_FIELD environment variable.
