Binary package hint: grub2
After installing Ubuntu 9.10 server edition using a serial console (on ttyS1), Grub2 fails to use the serial console as output device, and instead displays the following error messages:

These are the contents of /etc/default/grub:

This was fixed in grub-installer 1.49ubuntu5 in Lucid. This was fixed in bug https:/ /bugs.launchpad .net/ubuntu/ +source/ grub-installer/ +bug/524637 which I didn't realize was really a duplicate of this bug when I filed it.
