Bug#586621: error: cannot read `/boot/grub/core.img' correctly.

[Fabrice Lorrain]

Package: grub-pc
Severity: normal

Hello,

I got the very same problem here :

macmini core2 (i386)
refit as first stage bootloader
grub-pc as a second stage bootloader

Grub didn't boot since upgrade to grub-pc_1.98+20100617-1_i386.
Downgrading to grub-pc/grub-common to _1.98+20100614-2_i386 fixes this mess.

"aptitude hold" on both package until a proper fix is provided.
Please cc me when this is the case.

I'm interrested in understanding the following provided by debconf :
"grub-pc/mixed_legacy_and_grub2: true"
I though I removed/purge any dependancy/configuration against grub-legacy when
I migrated to grub2.

Thanks.

@+,
	Fab
