Bug#543632: grub-pc: postinst failure

[Antti-Juhani Kaijanaho]

Package: grub-pc
Version: 1.96+20090825-1
Severity: grave
Justification: renders package unusable

ajk at kukkaseppele:~$ dpkg --configure -a
dpkg: requested operation requires superuser privilege
ajk at kukkaseppele:~$ sudo dpkg --configure -a

dpkg: error processing grub-pc (--configure):

I added "set -x" to the postinst and got this:
ajk at kukkaseppele:~$ sudo dpkg --configure -a
Setting up grub-pc (1.96+20090825-1) ...
+ case "$1" in
