Hello all,

I was wondering if I could get some assistance. I currently have a system that is triple booting. Windows 7 was installed first, then 2 ubuntu variants were installed after that. The installs went fine.

In order it went like this: Windows 7, Ubuntu, Backtrack 5 R1.

All 3 OSs boot just fine. When I installed BT5 R1 I did not install a boot loader because I wanted to use the boot loader from Ubuntu. Grub is installed on the Ubuntu partition and I think this is the crux of my problem.

As per the instructions I ran an apt-get dist-upgrade from the terminal. However, part of the postinst hook script requires that it run update-grub. This causes the install to fail. Is there any way that I can bypass grub update so I can complete the dist-upgrade? TIA all!

Here is a snippet of the error.

Running depmod.
Examining /etc/kernel/postinst.d.
run-parts: executing /etc/kernel/postinst.d/pm-utils 3.2.6 /boot/vmlinuz-3.2.6
Running postinst hook script update-grub.

dpkg: error processing linux-image-3.2.6 (--configure):

Except it fails for both that and linux-image with the same problem.
