grub-pc installation fails on upgrade to quantal

[Kemel Zaidan aka Legendario]

This happened after I upgrade to quantal quetzal. Package grub-pc was not installed and i receive an error when trying to manually update grub even though grub-install works well:

# update-grub
Gerando grub.cfg ...
cat: /video.lst: Arquivo ou diretório não encontrado
/usr/sbin/grub-probe: erro: Falhou ao obter o caminho canônico de .
/usr/sbin/grub-probe: erro: não foi possível encontrar uma unidade GRUB para . Verifique o seu device.map.

Can you run "df" and post the results? And are you using a bios fake raid?
