Grub installation failure

[Samuel Walters-Nevet]

Installation process seemed to be going smoothly... until it didn't.
    Executing 'grub-install /dev/dm-0' failed. This is a fatal error.

It appears that you tried to install grub to /dev/dm-0, which is a logical volume. It must be installed to a physical drive, such as /dev/sda.

I encountered this issue also. I downloaded ubuntu-17.10.1-desktop-amd64.iso and created USB disk and tried to install Ubuntu using it. I did not specify anything, just pressing <enter> and selecting whatever is offered by default. It should not end like this.

Another report of the same bug: https://bugs.launchpad.net/ubuntu/+source/grub-installer/+bug/1708880

(That one is also incorrectly marked Invalid.)

[Janne Snabb (snabb)]

The same hardware and same default choices results with successfull installation (using grub-install /dev/sda) when using ubuntu-gnome-16.04.3-desktop-amd64.iso. So the bug has appeared after that version.

Please attach /var/log/partman.log after this happens.
