[Bug 1659448] [NEW] grub fails to install bootloader for zesty LVM with Encryption

[Jeremy Bicha]

Public bug reported:

Ubuntu GNOME 17.04 Alpha 2 candidate. Entire disk. Verified on both i386
and amd64. I am testing in VirtualBox. Only an 8GB virtual disk which
should be just barely enough for Ubuntu GNOME (see also LP: #1614810 )

Install completes successfully if I chose LVM, but if I chose to "Encrypt the Ubuntu installation for security", I get this error:
"Unable to install GRUB in /dev/sda
 Executing 'grub-install /dev/sda1' failed.
 This is a fatal error."

After clicking ok, I get another popup with three options (Choose a
different device to install the bootloader on, continue without a
bootloader, cancel the instllation). None of the options appear to do
anything.

I'm attaching screenshots.
