Comment 2 for bug 392748

I noticed the following in your DpkgTerminalLog.txt file:

Testing for an existing GRUB menu.lst file ... found: /boot/grub/menu.lst
Searching for splash image ... none found, skipping ...
expr: argument non numérique
User postinst hook script [/sbin/update-grub] exited with value 2
dpkg : erreur de traitement de linux-image-2.6.27-14-generic (--configure) :
 le sous-processus post-installation script a retourné une erreur de sortie d'état 2

This appears to be a duplciate of bug 193439 so I am marking it as such. Please continue to track this issue at that report. Thanks.
