[Bug 1386131] Re: Preseeding encrypted lvm fails instead of asking for password

[Colin Watson]

I looked at popping up a separate dialog here, but I think that's going
to involve an unreasonable amount of code duplication.  I think the
right answer here is probably to detect the situation and present the
user with the usual automatic partitioning page, but with the relevant
preseeded entries filled in and just the password entry boxes left
blank.  This is still going to be some work to get right.

Title:
  Preseeding encrypted lvm fails instead of asking for password

Status in ubiquity package in Ubuntu:
  Triaged

Bug description:
  I was trying to preseed creating encrypted lvm for enabling unattended
  installation with ubiquity 2.18.8.2 (in trusty).

  The encryption password has NOT been preseeded. I was expecting a UI
  with a password prompt.

  The installation fails before partitioning with a message box:
  "Keyfile creation failed. An error occurred while creating the keyfile."
