[Gilles DOFFE]

Binary package hint: debootstrap

when launching the following command, debootstrap hangup and X restarts, falling back to the login screen :
$ sudo debootstrap --include=ubuntu-desktop,linux-generic --components=main,restricted,universe,multiverse natty natty_i386

In attachment, the debootstrap.log.

Bug is always present in Oneiric.

I have investigated and found that changing the tty and come back to the tty running X avoid the problem.
I noticed then that when debootstrap hangs, X restart on the next available tty.

As a workaround I need to do before calling debootstrap command :
$ actualvt=$(fgconsole)
$ chvt `fgconsole --next-available` && chvt ${actualvt}

After this, previously mentionned debootstrap command works perfectly :
$ sudo debootstrap --include=ubuntu-desktop,linux-generic --components=main,restricted,universe,multiverse natty natty_i386

Seems to be "resolved" in trusty 14.04.1 64 bits.
