Comment 5 for bug 1822845

Of course I have grub in my system since first installation of Ubuntu
because I have still a windows partition and one more Linux partition. Grub
was always updated till this update.
I do have menu.lst see the enclosure.

The grub package in question is absolutely not used on your system. It
can't be, you have no menu.lst, which is the config file grub uses to know
what to boot.

I don't know why you have the 'grub' package installed. It is never
installed by default on an Ubuntu 16.04 system. The package name for grub
in 16.04 is 'grub-pc'.
