[kubuntu] Problems removing grub-customizer

I installed grub-customizer and it worked ok for a while. Then I started getting problems, mainly with the menu listings. As a backup I installed another linux dist on my second hard drive so I could boot from there if there were any problems. Then I proceeded to uninstall grub-customizer according to the FAQ listed here:

http://ubuntuforums.org/showthread.php?t=1664134

The suggested removal proceedure is item #7 at the end. When I got done and I ran update-grub, I got the following error:

/etc/grub.d/10_linux_proxy: 3: /etc/grub.d/10_linux_proxy: /etc/grub.d/proxifiedScripts/linux: not found
/etc/grub.d/10_linux_proxy: 3: /etc/grub.d/10_linux_proxy: /etc/grub.d/bin/grubcfg_proxy: not found

So I don't want to install this version to the MBR until I have cleared up the problem. I'm running Kubuntu 12.04

During an software upgrade I also got the following error which seems related"

"The following errors occurred while applying changes:

Package: grub-pc
Error: subprocess installed post-installation script returned error exit status 127"
