Bug#966575: grub-pc: error: symbol `grub_calloc' not found.

Hello,

My case was indeed a disk switch from USB to internal.

I probably had invoked directly grub-install (dunno if it'd make sense
to warn about the mismatch with debconf there?), now I know I should
rather use dpkg-reconfigure instead.

# debconf-get-selections |grep 'grub-pc/install_devices'

Thanks for the explanations!
