Description Dave Hodgins 2012-12-14 21:58:04 CET

In Mageia 3 beta 1, trying to install grub2 fails with the message
"Mandatory package grub2 is missing".

The problem is that /usr/lib/libDrakx/bootloader.pm is looking for
a binary program grub, lilo, or grub2, but there is no program
called grub2.

Simplest fix is to modify the grub2 package with
ln /sbin/grub2-install /sbin/grub2

Proper fix is to modify the message in
/usr/lib/libDrakX/do_pkgs.pm to
"Mandatory program %s is missing"
so it's easier to figure out what's wrong, and to modify
/usr/lib/libDrakX/bootloader.pm
to look for grub2-install, rather then grub2, as the program name.

I've confirmed this by running the ln command in a live dvd before
installing to the hard drive.

There's still a problem with the grub2 configuration, as it drops to
a grub shell on reboot, but the fix for that will require more digging.

No that's not the issue (we look for grub2-reboot) but as we are not yet able to read back grub2 config, we weren't installing grub2

I don't agree.  I've now successfully booted from a vb install, after installing
from a live dvd (kde i586).  To do so, I had to do the following ...

Before installing to the hard drive
ln /sbin/grub2-install /sbin/grub2

After installing to the hard drive, during which I selected grub2 on sda, ...
mkdir /a1
mount -t auto /dev/sda1 /a1
mount --bind /run /a1/run
(same with /dev, /proc, and /sys)
chroot /a1
grub2-mkconfig -o /boot/grub2/grub.cfg
grub2-install /dev/sda

Then, on reboot, grub2 is working.

So the problems with bootloader.pm are that it's looking for program called
grub2, which doesn't exist, and it's failing to run the grub2-mkconfig
command.  I'm not sure if the grub2-install is needed after the grub2-mkconfig
command, or not.

Comment 3 Dave Hodgins 2012-12-14 22:49:31 CET

Bug 8366 was about grub2-install not being available in stage2.

This bug is about bootloader.pm not working properly, when grub2 is
available, and is not fixed, so I'm reopening this bug.

Indeed a check was wrong.

Workaround for using grub2 with the classic installer.

After trying to install grub2, and getting the message
"Mandatory package grub2 is missing"
Alt+ctrl+f2
ln /mnt/sbin/grub2-install /mnt/sbin/grub2
Alt+ctrl+f7
Select ok twice.

Comment 6 Thierry Vignaud 2012-12-15 03:29:32 CET

This is already fixed in drakx-installer-stage2-15.13
