Content of /etc/crypttab when this crash occurs.

[Jean-Baptiste Lallement (jibel)]

This bug has been introduced by :

ecryptfs-utils (104-0ubuntu1)

  [ Dustin Kirkland ]
  * src/utils/ecryptfs-setup-swap: LP: #1172014
    - write crypttab entry using UUID

[Jean-Baptiste Lallement (jibel)]

I tried http://paste.ubuntu.com/7151118/ but then there is no swap after installation even if /etc/crypttab looks correct.

[Colin Watson (cjwatson)]

OK, so I have a fix for the ubiquity side of things, but the swap setup post-reboot still doesn't work. However, I think that's something that needs to be fixed elsewhere. I started a conversation with Dustin about it on IRC and we'll see where that goes:

14:53 <cjwatson> kirkland: so, bug 1172014
14:54 <cjwatson> kirkland: this change caused a regression in ubiquity; not really your fault, ubiquity needed to resolve the UUID= in crypttab because it explicitly zeroes the device
14:54 <cjwatson> kirkland: but more importantly, I can't actually make the swap setup work properly even after fixing that ubiquity bug
14:56 <cjwatson> kirkland: I think https://bugs.launchpad.net/ubuntu/+source/ecryptfs-utils/+bug/1172014/comments/9 has the right of it; the swap space is set up with a random key, there's no container, so how can it have a stable UUID?
14:58 <cjwatson> kirkland: indeed when I reboot after installation, re-point crypttab to /dev/sda5 so that I can cryptdisks_start, copy the new UUID into /etc/crypttab, and reboot, it still doesn't work

[Launchpad Janitor (janitor)]

This bug was fixed in the package ubiquity - 2.17.10

---------------
ubiquity (2.17.10) trusty; urgency=low

  [ Luke Yelavich ]
  * Set up atk label association for grub boot loader location combo box in
    advanced partition editor.
  * Add Super + Alt + S as an activation keystroke for the screen reader
    profile. This mirrors the same keystroke that can be used to activate the
    screen reader when in a Unity or GNOME desktop. The Control + S keystroke
    is still present for transitional purposes, so new users don't need to
    hunt for new information when they attempt to install trusty. It will be
    removed in trusty+1.

  [ Jason Gerard DeRose ]
  * ubiquity-dm: 'indicator-application-service' =>
    'indicator-application/indicator-application-service' (LP: #1297312).

  [ Colin Watson ]
  * Resolve LABEL= and UUID= entries in /etc/crypttab into real devices
    before trying to run swapoff and test -b on them (LP: #1296697).
  * Automatic update of included source packages: flash-kernel
    3.0~rc.4ubuntu48, grub-installer 1.78ubuntu18, partconf 1.45,
    partman-jfs 43, partman-lvm 90, partman-newworld 32.
