Grub error when bootstrap copy from wheezy

I am getting the following error when trying bootstrap copy from wheezy with the command "sudo lb config --bootstrap copy --debian-installer live --debian-installer-distribution daily". Could not find the solution even after googling and cleaning and build. Not able to understand what is wrong.. Could some one help me ?
