Comment 5 for bug 1450025

I can set french keymap on Debian Jessie with:

# Preseeding only locale sets language, country and locale.
d-i debian-installer/locale string fr_FR.UTF-8

# The values can also be preseeded individually for greater flexibility.
d-i debian-installer/language string fr
d-i debian-installer/country string FR

# Keyboard selection.
d-i keyboard-configuration/xkb-keymap select fr(latin9)

Setting the variant to oss does not work:

# Keyboard selection.
d-i keyboard-configuration/xkb-keymap select fr(oss)

Debugging the Debian Jessie keymap selection, I see that it's handled by /usr/share/console-setup/keyboard-configuration.config.

I pause the installer and put a set -x on top of this script in Ubuntu and it's never called.

Hope it will help.

Regards.
