[Bug 1169611] Re: 13.04 installation has damaged my luks partition

[Hugo Melo]

Hi Dmitrijs,

I had a ubuntu 12.10 and I chose the image
ubuntu-13.04-beta2-desktop-i386.iso.

I've used the unetbootin application for creating an installation media
using my pendrive (that's the /dev/sdb).

The installation finished successfully and I am able to use raring
without problems.

I've used the "something else" option and defined /dev/ubuntu/raring as my root partition and /dev/ubuntu/swap as my encrypted swap partition. Nothing more.
The encryption was taken using the installer. If I remember well, I had an option of using the partition as luks encrypted and it showed me an input for password (did not let me choose random passphrase).

After the installation was finished I asked it to restart. After
restart, I noted it was not showing the text saying "please type the
password for your swap encrypted partition. It just presented me the
dark input and got stuck. I've switched the consoles and got the message
asking the passphrase.

After boot, I was not able to luksOpen my home partition anymore. It's
still untouched.

Title:
  13.04 installation has damaged my luks partition

Status in “ubiquity” package in Ubuntu:

Bug description:
  Some days ago I've installed ubuntu 13.04 beta2 release on a clean
  partition I had.

  I've chosen in the installer to not touch my home partition as it's
  encrypted and I doubted it would not understand that.

  I chose the root partition and asked to encrypt my swap partition.

  After installation I couldn't open my home partition any more. It keep
  saying:

    hugo at scare:~$ sudo cryptsetup luksOpen /dev/ubuntu/home home_crypt
  Device /dev/ubuntu/home is not a valid LUKS device.

  I don't know what the installer thought about my partition but I expected it to not touch that.
  I am still trying to not go crazy about it but I didn't have the luks partition header on my backups and I have almost zero hope on recovering that. I just expect it to be fixed in a near future.

  It seems  ubuntu installer still has little support for lvm+luks
  partitions on installer.
