Expected behavior:
Command 'grub-emu-lite -d /usr/lib/grub'
starts properly in terminal UI mode ('normal.mod' module)

Actual behavior:
Command 'grub-emu-lite -d /usr/lib/grub'
fail to start properly and starts only in "rescue mode" instead.

Command output:
$ grub-emu-lite -d /usr/lib/grub
error: incompatible license.
Entering rescue mode...
grub rescue> normal
Unknown command `normal'.
