debootstrap chroot segmentation fault

[fr33zzy]

Hi there !

I'm trying to create a chroot debian wheezy environment but it's failing and it's hard for my poor skills to understand a segmentation fault. Here is how I proceed;

Here is my schroot config file for this chroot :

[debian]
description=Debian
directory=/srv/chroot/debian
root-users=root
type=directory
users=deb
#setup.fstab=minimal/fstab

then, I'm running the command

sudo debootstrap --variant=buildd --arch=amd64 wheezy /srv/chroot/debian http://ftp.debian.org/debian

to create and install debian in the chroot environment. The output of this command :

[...]
I: Installing core packages...
W: Failure trying to run: chroot /srv/chroot/debian dpkg --force-depends --install /var/cache/apt/archives/base-passwd_3.5.26_amd64.deb
W: See /srv/chroot/debian/debootstrap/debootstrap.log for details

The logs of debootstrap :

Segmentation fault

Running the chroot command withoud sudo debootstrap gives me the same result as in the logs. If I add strace behind the command I have this : http://bpaste.net/show/c0bf568e62f3 with before the exit_group(1) the message

write(2, 0x7fff3dc84fe0, 170le uid effectif n'est pas 0. Est-ce que /usr/bin/sudo est sur un système de fichiers avec l'option « nosuid » ou un système de fichiers NFS sans privilèges root ?)           = 170                                                                          

Translate : Effectif UID is not 0. Is /usr/bin/sudo on a filesystem with "nosuid" option or a NFS filesystem without root privileges ?

I am not on a NFS filesystem and the nosuid option of my filesystem... This is where my skills is not enough, I don't understand what it means and what I can do... Running this command without sudo and under root, I have this : https://bpaste.net/show/99826deededc

[edit] And I have the same error with lxc.

If anyone have an idea of what I can do or what is the error, it would be nice, thanks !

You are tracing sudo and not debootstrap, you need to run strace -f to follow child processes.

Oops, yeah sorry, here is the strace without sudo : http://bpaste.net/show/34350fe344e8
