Public bug reported: I tried installing a daily build of 16.04. Fatal error during installation: grub failed to install on /dev/sda.
I used custom partition setup to format an existing partition as / (btrfs) and mounting another existing partition as /home (ext4). I've never tried btrfs as a root filesystem before, but I was feeling adventurous. The installer gave me no indication that there may be problems with btrfs root filesystems, but I'll try again with / as ext4.
