Yes.

This uniquely maps to /dev/sdd2 on your system.  So you will want to
un-comment the line for /boot/efi in /etc/fstab, replacing
'/dev/mapper/isw_cacfjebbfc_Volume0p2' with 'UUID=8fb4f0b4-4ab3-4260-914b-639abab26972';
then run 'sudo mount /boot/efi'; then finish your upgrade.

Do you recall having Intel Software RAID on this system previously?  Can you
say how you went about disabling that?

Title:
  Ubuntu system broken after upgrade from 15.10 to 16.04

Status in shim-signed package in Ubuntu:
  Incomplete

Bug description:
  After unfortunate click on upgrade to 16.04 my system is now almost
  useless (fortunately enough I can still work with a windows 10 VM.. )

  Seems like grub is failing to find efi folder so there is an avalanche
  of broken things - from shim to unity.

  I'll try to open from the broken system and add some more information.
