Thanks. That seemed to work for Japanese, but not for Dutch, which seems to error out on me: Code: vincent@vincent-eeepc:~$ sudo locale-gen nl_NL.UTF-8 Generating locales... nl_NL.UTF-8... cannot open locale definition file `nl_NL': No such file or directory failed Generation complete. It's not in locale -a afterwards. Installing language-pack-nl and language-pack-nl-base in Ubuntu's package manager made no difference; in fact, these packages' post-installation triggers are supposed to do this and fail too.
