Public bug reported:
For some reason the installation fails if you format the disk before
install Ubuntu on it. Looking at /var/log/syslog I saw those messages:
Oct 3 00:21:28 in-target: Installing for powerpc-ieee1275 platform.
Oct 3 00:21:28 in-target: grub-install: error: the PReP partition is not
empty. If you are sure you want to use it, run dd to clear it: `dd if=/dev/zero
of=/dev/sda1'.
Oct 3 00:21:28 in-target: dpkg: error processing package grub-ieee1275
(--configure):
Oct 3 00:21:28 in-target: subprocess installed post-installation script
returned error exit status 1
PReP partition needs to empty or have an old elf inside it, otherwise,
GRUB will refuse to install it.
Steps:
- qemu-img create disk1.raw 10G
- mkfs.ext4 -F disk1.raw
- qemu-system-ppc64 -enable-kvm -M pseries -smp 1 -m 1G -nographic -nodefaults
-serial stdio -drive file=disk1.raw -cdrom
../ubuntu_daily/utopic-server-ppc64el_2014-10-02.iso -boot d
- Default options. Use "Guided - use entire disk"
Using daily image from Oct 2.
