[Bug 1630327] Re: Ubiquity crashes during final configuration if user requests encrypted home partition

[Sebastien HUART]

I commented the "user-setup/encrypt-home"  setting (comment #6) in the preseed file I used back then, and the user creation step was successful, but I didn't try to uncomment it again 
.....
# Set to true if you want to encrypt the first user's home directory.
#d-i user-setup/encrypt-home boolean true
.....
after that I could install hundreds of xenial laptops quite smoothly (last ones yesterday)

As I try to guess in comment #6 above, setting this to true might have had side effects with the OEM user (required by oem/ubiquity)  
I will try uncommenting that preseed setting again with last release of xenial today.

Title:
  Ubiquity crashes during final configuration if user requests encrypted
  home partition

Status in ubiquity package in Ubuntu:
  Incomplete

Bug description:
  If I select 'encrypt my home directory' in the user account setup
  dialog (last manual step of the installation process) and click
  'Continue', Ubiquity starts applying the final configuration changes
  and crashes about 4-5 seconds later (logs attached).  This is 100%
  reproducible across reboots on a vanilla 16.04 install (new System76
  laptop, right out of the box).  Going through the process without
  requesting an encrypted home directory yields normal completion.

  From the symptoms reported by other users this is quite possibly a
  duplicate of one or more of the issues listed on
  https://wiki.ubuntu.com/UbuntuBugDay/20140710 (and thus at least a
  couple of years old), but few of those were investigated very
  thoroughly so it's impossible to be sure.
