Installing 13.04 crashes when installing GRUB

[Michael Barraclough]

Installing 13.04 with raided partitions for /, /boot and /home. Everything is ok except that GRUB won't install.

/dev/sdh + /dev/sdi = /dev/md0 (/root) and /dev/md1 (/) [MBR based]
/dev/sda + /dev/sdb + /dev/sdc = /dev/md2 (/home) [GPT based]

Tried installing GRUB on /dev/sdh, /dev/sdi, /dev/md0 and /dev/md0p1 - all fail and crash the installer

Status changed to 'Confirmed' because the bug affects multiple users.

13.04 reached end of life some time ago and is no longer supported, so I am closing this report.

[John W. O'Brien (neirbowj)]

Seems to affect 14.04 too. Reopen or refile?

[Phillip Susi (psusi)]

The installer automatically files a new bug report when installing grub fails.
