Hi,
in i18n.cfg there are still for many languages the codes lang=C. These codes should be replaced according
https://www.debian.org/international/l10n/po/ja_JP
for
Czech (Cesky) with lang=cs_CZ
Danish (Dansk) with lang=da_DK
Greek (Ellinika) with lang=el_GR
Croatian (Hrvatski) with lang=hr_HR
Icelandic (Islenska) with lang=is_IS
Japanese with lang=ja_JP
Hungarian (Magyar) with lang=hu_HU
Dutch (Nederlands) with lang=nl_NL
Polish (Polski) with lang=pl_PL
Slovenian (Slovenski) with lang=sl_SL
Finnish (Suomi) with lang=fi_FI
Svedish (Svenska) with lang=sv_SE and
Turkish (Turkce) with lang=tr_TR for both keyboard mappings.
In Norway there are two official Norwegian languages Bokmål (Oslo, E6 area) and Nynorsk (Bergen area).
So please edit the line for Norwegian (Norsk)
Norsk (Bokmal) with lang=nb_NO
and add lines for
Norsk (Nynorsk) with lang=nn_NO
