None of the answers I could find online work. Most are obviously outdated, but even the "recent" one from here: Set keyboard layout in debian wheezy with preseed
Provided by Lion (2023)
Simply gets ignored. Installer finishes and I end up with the wrong (not qwertz despite setting every option to German) keyboard layout.
#_preseed_V1
d-i debian-installer/language string de
d-i debian-installer/country string DE
d-i debian-installer/locale string de_DE.UTF-8
Keyboard selection.
d-i keyboard-configuration/xkb-keymap select de
Network configuration
...
I literally set every option that seemed somehow related to locales to German in hope not to somehow mess up the keyboard and it still doesn't work.
How to select a German keyboard setting (QWERTZ) in a preseed file?
