[Bug 1362333] Re: After reboot of Ubuntu installation, password for LVM encryption is not accepted

[Andy Whitcroft]

Experimenting on the image I think I am able to say that the "plymouth
ask-for-password --prompt FOO" functionality is not working.  If you
envoke /lib/cryptsetup/askpass FOO and type a password you will get the
password string as text on stdout, this does not occur with plymouth's
ask-for-password, the prompt is shown and can be interacted but the
client simply exits 1 rather then emitting the typed text.

Title:
  After reboot of Ubuntu installation,  password for LVM encryption is
  not accepted

Status in “ubiquity” package in Ubuntu:
  Confirmed

Bug description:
  I have tried several times to perform an installation of Gnome Ubuntu x64 (Utopic Beta 1  26/08/2014 ISO), after reboot, you are asked to insert your passphrase, but it is not accepted it keeps on displaying that the passphrase is not correct even though I am inserting the correct one, and so booting of Ubuntu Gnome isn't possible after install.
  I have performed the installation on a Virtualbox VM and I still have it if you need something else.
  I am attaching the /var/log directory of the /dev/sda5 LVM volume that I could manage to unencrypt, when unencrypting it manually the password was accepted and /dev/sda5 mounted, so I am sure the password I was trying to insert was the correct one.
  This is the test I was carrying out when I detected this bug:
  http://iso.qa.ubuntu.com/qatracker/testcases/1451/info.
  This is the ISO I tested on: http://cdimage.ubuntu.com/ubuntu-gnome/daily-live/20140826/utopic-desktop-amd64.iso.
