[Bug 1450025] Re: Unable to preseed language

[Mathieu Trudel-Lapierre]

I'm easily able to reproduce this behavior in Debian and Ubuntu, and I'm
not denying it looks like there is a bug here in localechooser code, one
that we'll address.

However, I am able to preseed the language despite that error message
showing up, so I'll further reduce the bug priority to Low.

FWIW, I've been using "language=fr" as a parameter added on the command-
line, which is also equivalent to picking French in the menu for the
Server CD. I've also tried the same on mini.iso (so, fairly similar to a
PXE boot), with the same behavior. In all my tests, the installer *does*
come up in french.

Could you please tell us more about the bug? Should we read from this
that the resulting installed system does not come up in french?

Title:
  Unable to preseed language

Status in localechooser package in Ubuntu:
  Incomplete

Bug description:
  Hello,

  I'm trying to preseed a 14.04.2 installation with hands-off[0] and
  found a bug in do_pressed[1].

  When looking up known languages[2] a $lang variable is used bug comes
  from nowhere (empty), I think it should be $ps_language.

  I started an installation, pause it (thanks hands-off) and add some
  set -x in some script to debug.

  Here are the logs from localechooser do_preseed line 162[3] to 179[4]:

  This results in not using the preseeded language[5]:
