package grub-pc 2.02~beta2-9ubuntu1 failed t install/upgrade: subprocess script post-installation installed returned error output status 1

Problem configuring grub after upgrading 12.04LTS to 14.04LTS.

The hardware is a Fujitsu Siemens Primergy RX100 S7 server with a RAID1 configured storage.
The first time I installed Ubuntu on this server i had to use the desktop version (strange!) because the server installer couldn't find the hard drive, but the desktop version could!

Now I did the release upgrade and it failed to update grub.

To solve this problem I rebooted the machine,the grub console prompt showed, and I wrote:
grub> set root=(hd0,1) <- my boot partition
grub> linux /vmlinuz-3.13.0-46-generic root=/dev/mapper/ddf1_4c............p5 <- the mapped root partition
grub> initrd /initrd.img-3.13.0-46-generic
grub> boot

The machine successfully booted and then I did:
# sudo su
# update-grub
# grub-install /dev/mapper/ddf1_4c........ <- the mapped hardrive identifier

Let's just make sure to begin with that the partition is indeed what we expect:
/dev/mapper/ddf1_4c53492020202020808627c3000000004711471100001450p1

^ This should be the partition used for /boot.

Could you also please re-run grub-install with the '-v' switch so we have additional information about how it attempts to setup the bootloader?
