Title:
  grub-efi-amd64-signed package failed to install into '/'

Status in grub-installer package in Ubuntu:
  New

Bug description:
   Installing Ubuntu Mate 18.04
      Got this error Hours ago when installing with ext4  for '/' and '/home'

  Installation was aborted.

  
    Q&A had bug about ext4 - with this problem. SO, tried again with ext2 file systems.
  ... get Same error...
  Spent  an hour or two looking through problems and solutions - and did not see
  a focused solution to the problem.

  I have installed 16.04 on newer PCs with UEFI without any problem.

  Help!

  Thanks in advance, Jane and Jay.
