[Bug 1423830] Re: Trusty -> Vivid upgrade via live DVD froze (UEFI dual boot)

[Erick Brunzell]

I may not get back to testing in regards to this bug before Vivid
releases but I've been following bug #1418706 and suspect that the two
may be related - but not duplicates - so I wanted to make a note to
myself for when I do get back to this. Specifically look at comments 33
and 34.

Title:
  Trusty -> Vivid upgrade via live DVD froze (UEFI dual boot)

Status in ubiquity package in Ubuntu:
  Incomplete

Bug description:
  I'm not altogether certain what happened here because I'm almost
  totally new to the whole EFI boot process but I was testing Ubuntu
  GNOME Vivid 20150219 amd64 to see how we now handle upgrades via iso
  in a dual boot with Windows and the upgrade/installation froze saying,
  "Removing conflicting operating system files....".

  I sent myself several pictures via PM because I couldn't "kill"
  ubiquity - top doesn't even show it running - so I'll follow up more
  later. I am attaching one screenshot of the frozen process.
