[Bug 1070934] Re: /scripts/local/cryptroot can't find /dev/mapper/vgubuntu-root

[Steve Langasek]

First thing's first: to get you unblocked on this, please note that from
the boot menu you should be able to drill down into "Advanced options
for Ubuntu" and boot to your previous kernel (and initramfs) from 12.04.
This should allow you to boot the 12.10 system using the 12.04 kernel
and get you back on your feet.

Now, I notice that in your bug report you list "/dev/mapper-vgubuntu-
root".  Can you confirm the spelling here?  Because this is definitely
an incorrect device name - it should instead be /dev/mapper/vgubuntu-
root.  So that could be your problem.  In that case, the problem will
probably also affect trying to boot the 12.04 kernel, since the boot
menu entry will have been changed even if the initramfs hasn't.

Title:
  /scripts/local/cryptroot can't find /dev/mapper/vgubuntu-root

Status in “cryptsetup” package in Ubuntu:
  Incomplete

Bug description:
  I upgraded my netbook from Ubuntu 12.04 to 12.10 and now it won't boot.
  It is encrypted using cryptsetup and a LVM with a sperate home partition, that means 4 partitions in total:
  - /dev/sda1 unencrypted, mounted to /boot
  - /dev/sda2 encrypted as lukslvm containing vgubuntu-root (/), vgubuntu-home (/home) and swap

  After I've typed in my password, I get the following error message:
  /scripts/local/cryptroot: line 1: can't open /dev/mapper-vgubuntu-root: no such file

  Then, some other processes are started but at some point everything
  just stops and I don't get to a working system.

  I appreciate any kind of help. My computer simply doesn't work at all
  so I'd be glad if this could be solved soon. Thanks.
