When using the tool xen-create-image I get an error with the debootstrap process.

So I tried running:

chroot /tmp/ubuntu dpkg --force-depends --install /var/cache/apt/archives/debconf_1.5.42ubuntu1_all.deb

The output: Illegal instruction (core dumped) Seems to imply some fundamental problem with debconf or something. Is there a way to work around this problem so I can get the debootstrap script to run without errors?



apt-get install dialog

Found it here after having the same problem. (I did debootstrap wheezy --variant=minbase)

Alternatively, you can use

export DEBIAN_FRONTEND=noninteractive

before running apt-get. This will fallback to a pure text console interface which also works in scripts or Dockerfiles.

    It's export DEBIAN_FRONTEND=noninteractive which turns off all questions. And DEBIAN_FRONTEND=teletype is also an option Dec 6 '15 at 23:43

I had the same issue twice by now and it was caused by a messed up package. Running the following command in terminal should fix the problems:

apt-get update && apt-get dist-upgrade
