Comment 6 for bug 1407790

Hey, the same thing is happening to me. I saw that @Phillip Susi said that "The script is checking to see if /etc/grub.d/00_header still references it, which it shouldn't as it has been removed". Do you mean that the script has been removed or that the script has changed and is no longer referencing it ?
I am doing an upgrade from 12.04 to 14.04 then to 16.04. From what i saw, the 00_header does not change from 12 -> 14 -> 16.
