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

[Stephan Diestelhorst]

I believe I had the same issue when upgrading from 11.10 -> 12.04 on a
LUKS -> LVM setup.  I believe my issue was caused by a superflous
lvm=/dev/... for each device in /etc/crypttab.  That seems to have been
picked up by update-initramfs and caused funny entries (with two
"lvm=...") in (initrd)/conf/conf.d/cryptroot.

I had picked those entries in /etc/crypttab up from some (old) tutorial
from the web.  Seems they were not very helpful after all.

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

Status in “cryptsetup” package in Ubuntu:
  Fix Released

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.
