Public bug reported:
Binary package hint: ubiquity
I have three disks for software raid that I have set up as
/dev/sd[abc]1. The third disk is slower than the first two, so I have it
marked as "writemostly" through mdadm. They are assembled onto raid
array /dev/md0.
However, ubiquity tries to guess that the bootloader should be installed
on all /dev/sd[abc]. That is fantastically-smart behaviour.
However, when probing the array properties, it gets confused. Output of
/var/log/messages is:
Nov 24 02:52:38 ubuntu grub-installer: info: Installing grub on '/dev/sda

more information.
Nov 24 02:52:44 ubuntu grub-installer: error: Running 'grub-install
--no-floppy --force "writemostly"' failed.
At this point, I get the graphical "Bootloader install failed" dialog,
with "How would you like to proceed?"
The problem is that the "okay" button is always greyed out, and thus the
installation hangs/fails.
