[Bug 1273261] Re: Cryptsetup error during boot: /scripts/local-top/cryptroot: line 1: can't open /dev/mapper/ubuntu--vg-root: no such file

[cljokla]

I just had this happen to me today.  I'm on 14.04LTS and it was current
on it's patches as of 10/2/2014.   I've been running 14.04LTS on this PC
since it was release and had no problems until today.

I do have another observation to add.  I have a laptop and I encrypted
the whole disk.  I started it up this morning and was working fine for
about an hour.  I opened a LibreOffice database and did some work in it
just fine, then opened LibreOffice Calc.  The Calc came up slow and was
responding slow.  It wasn't intolerable, but slower than normail.  I
jumped back to the File database and found it was slow too.  I checked
and my Firefox and Remmina RDP session were still running fine.  So I
figure it was a LibreOffice glitch.  I finished what I was working on
then closed the Libre apps and checked to make sure all their processes
had closed, then I reopened the Libre apps and found them still slow.
So I decided to reboot.  I closed all my apps, and rebooted.  It came up
normally, asked for my password, show the encrypted drive was good and
then just sat there on the Ubuntu logo.  So after a few minutes I tried
a cold boot, same thing.  So I rebooted into recovery and it froze too.

Has the encrypted disk got corrupted in such a way that it's no longer
useable?  Or is this really a bug?

Has anyone had any success repairing this?

  Confirmed

Bug description:
  While booting cryptsetup outputs following error: /scripts/local-
  top/cryptroot: line 1: can't open /dev/mapper/ubuntu--vg-root: no such
  file, seems to be not related to this particular installation as saw
  the same output on other machines, also seems to be nothing major as
  everything boots fine, so just reporting to let you know it's there.
