Ubuntu 20.10 Live, debian-installer/language=de not working anymore

[beta-tester]

hi,

i tried to PXE boot Ubuntu 20.10 Live from ubuntu-20.10-desktop-amd64.iso (2020-10-22 14:31)
but i have issues with setting the locale by using bootoptions.

using the following additional boot options to setup locale and keyboard layout:
debian-installer/language=de
console-setup/layoutcode=de
keyboard-configuration/layoutcode=de
keyboard-configuration/variant=German

here the full pxe boot entries:
KERNEL http://192.168.1.1/srv/nfs/ubuntu-x64/casper/vmlinuz
INITRD http://192.168.1.1/srv/nfs/ubuntu-x64/casper/initrd
APPEND nfsroot=192.168.1.1:/srv/nfs/ubuntu-x64 ro netboot=nfs ip=dhcp file=/cdrom/preseed/ubuntu.seed boot=casper -- debian-installer/language=de console-setup/layoutcode=de keyboard-configuration/layoutcode=de keyboard-configuration/variant=German

after sucessfull PXE boot into Ubuntu 20.10 Live, the locale is set to aa_DJ.UTF-8

LANG=aa_DJ.UTF-8
LANGUAGE=
LC_CTYPE="aa_DJ.UTF-8"
LC_NUMERIC="aa_DJ.UTF-8"
LC_TIME="aa_DJ.UTF-8"
LC_COLLATE="aa_DJ.UTF-8"
LC_MONETARY="aa_DJ.UTF-8"
LC_MESSAGES="aa_DJ.UTF-8"
LC_PAPER="aa_DJ.UTF-8"
LC_NAME="aa_DJ.UTF-8"
LC_ADDRESS="aa_DJ.UTF-8"
LC_TELEPHONE="aa_DJ.UTF-8"
LC_MEASUREMENT="aa_DJ.UTF-8"
LC_IDENTIFICATION="aa_DJ.UTF-8"
LC_ALL=

but the locale sould be set to de_DE.UTF-8 as expected (and as it was with ubuntu 20.04):

LANG=de_DE.UTF-8
LANGUAGE=
LC_CTYPE="de_DE.UTF-8"
LC_NUMERIC="de_DE.UTF-8"
LC_TIME="de_DE.UTF-8"
LC_COLLATE="de_DE.UTF-8"
LC_MONETARY="de_DE.UTF-8"
LC_MESSAGES="de_DE.UTF-8"
LC_PAPER="de_DE.UTF-8"
LC_NAME="de_DE.UTF-8"
LC_ADDRESS="de_DE.UTF-8"
LC_TELEPHONE="de_DE.UTF-8"
LC_MEASUREMENT="de_DE.UTF-8"
LC_IDENTIFICATION="de_DE.UTF-8"
LC_ALL=

it was not an issue with Ubuntu 20.04 Live

when i left out the boot options for locale settings at booting 20.10, the resulting locale is set to C.UTF-8

LANG=C.UTF-8
LANGUAGE=
LC_CTYPE="C.UTF-8"
LC_NUMERIC="C.UTF-8"
LC_TIME="C.UTF-8"
LC_COLLATE="C.UTF-8"
LC_MONETARY="C.UTF-8"
LC_MESSAGES="C.UTF-8"
LC_PAPER="C.UTF-8"
LC_NAME="C.UTF-8"
LC_ADDRESS="C.UTF-8"
LC_TELEPHONE="C.UTF-8"
LC_MEASUREMENT="C.UTF-8"
LC_IDENTIFICATION="C.UTF-8"
LC_ALL=

here the PXE server project i used: https://github.com/beta-tester/RPi-PXE-Server

i think this is a bug.

when looking to the casper.log, i can see the folowing lines:

+ '[' -e /conf/param.conf ]
+ /scripts/casper-bottom/14locales
Begin: Setting up locales... ... grep: /root/usr/share/localechooser/languagelist: No such file or directory
Generating locales (this might take a while)...
  aa_DJ.UTF-8... done
Generation complete.
done.

looks like there is something missing.

thanks to comments from Gunnar Hjalmarsson
https://askubuntu.com/questions/1296105/ubuntu-20-10-live-locale-set-to-aa-dj-when-bootoption-tells-to-setup-with-loca

i got it working.

when using `debian-installer/locale=de_DE.UTF-8`
instead of `debian-installer/language=de`

the locale and language is set up as expected.

reading https://help.ubuntu.com/lts/installation-guide/amd64/ch05s03.html#preseed-args
the option `debian-installer/language=de` should work, but it doesn't with Ubuntu 20.10 Live.

i also tried the both options `debian-installer/language=de debian-installer/country=DE` without success.
