Bug#365831: xserver-xorg: uninstallable on clean system, preinst exit status 10

["Richard Burton" <richardaburton@hotmail.com>]

Package: xserver-xorg
Version: 1:7.0.15
Severity: grave

xserver-xorg cannot be installed on a clean system. "clean system" was 
created
using DFS cd to bootstrap unstable. Previously I would have installed
xwindows-system-core & gnome-desktop-environment to get my desktop.

I wasn't totally sure what x-windows-system-core translated to with xorg, so 
I
guessed at xserver-xorg-core. This installed fine, but gdm wouldn't start
(no /etc/X11/X symlink), so I proceeded to try and install xserver-xorg 
(which
thinking about it is probably the one that creates this symlink, as well as 
the
xorg config file).

xserver-xorg gives:
"subprocess pre-installation script returned error exit status 10"

Rebuilding the package with -x in the preinst I can see that it's failing at
the call to /use/share/debconf/frontend. Sticking a couple of prints in 
there
I can see it's $confmodule->exitcode that's 10 on after the
while ($confmodule->communicate) loop.

I don't know anything about debconf, so I can't diagnose any further without
some instruction. Please let me know what else I can do...


Richard.
