Setting up linux-image-2.6.18-5-686 (2.6.18.dfsg.1-17) ...

 Hmm. The package shipped with a symbolic link /lib/modules/2.6.18-5-686/source
 However, I can not read the target: No such file or directory
 Therefore, I am deleting /lib/modules/2.6.18-5-686/source

Running depmod.
Finding valid ramdisk creators.
Using mkinitramfs-kpkg to build the ramdisk.
Running postinst hook script /sbin/update-grub.

file and follow its instructions.

You shouldn't call /sbin/update-grub. Please call /usr/sbin/update-grub instead!
