Public bug reported: during upgrading of lubuntu 14.10 on my Asus X200CA laptop to lubuntu 17.04, the grub2 installation part failed. however, on restarting the computer, the laptop booted normally, but got this error automatically after booting. not much of an issue for me, but reporting nonetheless.
