[Bug 1768687] [NEW] Ubuntu 18.04 install fails at grub and error configuring grub-efi-amd64-signed

[Kamrul Hasan]

Public bug reported:

I was trying to install ubuntu 18.04 on Extended Partition and at the
point of installing grub the installation process was failing. Note that
I have windows installed in one primary partition, I have Ubuntu 16.04
on another primary partition.

I am failing to install ubuntu 18.04 on extended partition. The grub is
not installing and whole installing process is crashing.
