Title:
  utopic upgrade lost the 'ubuntu' EFI variable

Status in “ubuntu-release-upgrader” package in Ubuntu:
  New

Bug description:
  My upgrade from trusty to utopic on my thinkpad X240 with a LUKS-
  encrypted / went smoothly enough.  The only oddity was a period when I
  had to click into the terminal details and hit enter for it to
  complete.  I'm not entirely sure what was waiting for input or if it
  is relevant, but when I rebooted I found myself without the 'ubuntu'
  entry in the EFI variables.

  I didn't realise this at first, and the Canonical Technical Support
  folks advised me to use this tool: https://help.ubuntu.com/community
  /Boot-Repair which made the problem worse (It did not fix the EFI
  problem, and removed dm-crypt.ko from my initrd).  I had to run
  efibootmgr to put it back, and start from an old kernel that had an
  unmolested initrd.

  I've restored boot functionality on my laptop now, but I'm curious
  what caused it to happen in the first place.
