Title:
  FAIL: installing grub to target devices

Status in MAAS:
  New

Bug description:
  MAAS: 2.6.2

  Today deployment is constantly failing. I've tried recommissioning and
  went through a live DVD of Gparted and wiped the storages to be sure.
  Still, I can't get past this:

  start: cmd-install/stage-curthooks/builtin/cmd-curthooks/install-grub: installing grub to target devices
  setup grub on target /tmp/tmplwfmv7xv/target
  Found primary UEFI ESP: sda-part1
  finish: cmd-install/stage-curthooks/builtin/cmd-curthooks/install-grub: FAIL: installing grub to target devices
  finish: cmd-install/stage-curthooks/builtin/cmd-curthooks/configuring-bootloader: FAIL: configuring target system bootloader
  finish: cmd-install/stage-curthooks/builtin/cmd-curthooks: FAIL: curtin command curthooks

      if item['type'] == 'mount' and item['path'] == '/boot/efi':
  KeyError: 'path'
  'path'
  Stderr: ''

  Previous deployment that worked used: curtin: Installation started. (19.3-26-g82f23e3d-0ubuntu1~18.04.1)
  This failing one uses: curtin: Installation started. (20.1-2-g42a9667f-0ubuntu1~18.04.1)
