Comment 2 for bug 399949

Seeing as how the bootloader install is what kills ubiquity, I attempted running the following to reinstall GRUB. Check out the "[: 494: =: unexpected operator" error.

ubuntu@ubuntu:~$ sudo mount /dev/sdc1 /mnt
ubuntu@ubuntu:~$ sudo grub-install --root-directory=/mnt /dev/sdc
Probing devices to guess BIOS drives. This may take a long time.
grub-probe: error: Cannot open `/boot/grub/device.map'
[: 494: =: unexpected operator
Installing GRUB to /dev/sdc as (hd2)...
Installation finished. No error reported.
This is the contents of the device map /mnt/boot/grub/device.map.
Check if this is correct or not. If any of the lines is incorrect,
fix it and re-run the script `grub-install'.

(hd0) /dev/sda
