This seems to be a packaging issue. "language-pack-de-base" installs the "gimp*.mo" files at "/usr/share/locale-langpack/de/LC_MESSAGES", while gimp searches them at "/usr/share/locale/de/LC_MESSAGES". After manually copying "/usr/share/locale-langpack/de/LC_MESSAGES/gimp*" to "/usr/share/locale/de/LC_MESSAGES/", the entry for the new language is shown in the "Language" dropdown.
Probably "gimp_locale_directory()" returns the wrong directory (called in gimp_language_store_parser_init() at https://gitlab.gnome.org/GNOME/gimp/-/blob/0c8a7891f75a9f41cd36fc0efe2ad506a53d0a15/app/widgets/gimplanguagestore- parser.c). The "gimp_locale_directory()" function either uses the value from the "GIMP2_LOCALEDIR" environment variable, OR a compile time absolute directory ("LOCALEDIR") OR the directory "share/locale" below the GIMP installation directory, in that order (see "gimp_locale_directory()" at https://gitlab.gnome.org/GNOME/gimp/-/blob/0c8a7891f75a9f41cd36fc0efe2ad506a53d0a15/libgimpbase/gimpenv.c). A workaround is to set the GIMP2_LOCALEDIR to "/usr/share/locale- langpack" before launching gimp. The solution is probably to set the LOCALEDIR compile time variable to "/usr/share/locale-langpack" when building gimp. -- You received this bug notification because you are a member of Edubuntu Bugsquad, which is subscribed to gimp in Ubuntu. https://bugs.launchpad.net/bugs/1875829 Title: in kubuntu 20.04 GIMP offers only English language To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gimp/+bug/1875829/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~edubuntu-bugs Post to : edubuntu-bugs@lists.launchpad.net Unsubscribe : https://launchpad.net/~edubuntu-bugs More help : https://help.launchpad.net/ListHelp
