This is a forward of the bug reported in the Debian bug tracker: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=845788 Currently the values used to fill the combos in the formats kcm come from a: QLocale::matchingLocales(QLocale::AnyLanguage, QLocale::AnyScript, QLocale::AnyCountry); Sadly this includes values that are not supported by the system locales libraries, as qt uses it's own locales database. Even more, this disregards the fact that most users have only a subset of the locales generated (see the output of locales -a to obtain a list of the currently available locales). The Debian report has been reassigned to the qt maintainers, and it might be that the issue can be addressed on the qt side. As per suggestion of Kai Uwe Broulik via irc I'm forwarding the issue here to raise the issue awareness. The original report from "Jeroen N. Witmond" reads: I live in the Netherlands but I prefer to communicate with my computer systems in English. I have answered the related questions during the installation of Stretch Alpha 8 accordingly. Now a number of applications complain about the locale. An example is: jeroen@zandbak:~$ man ssh-keygen man: can't set the locale; make sure $LC_* and $LANG are correct The $LC_* variables appear to not be set. jeroen@zandbak:~$ echo $LANG en_NL.UTF-8 jeroen@zandbak:~$ echo $LANGUAGE en_US:en Some digging showed that en_NL.UTF-8 is an incorrect value, and that it is set in files: jeroen@zandbak:~/.config$ grep en_NL * plasma-locale-settings.sh:export LANG=en_NL.UTF-8 plasma-localerc:LANG=en_NL.UTF-8 Questions: 1. Can I overwrite the values in these files manually, or do I need to use some dialog? 2. How to keep other users from stubling on this problem? Regards, jeroen. Happy hacking,
Hi Maximiliano, Jeroen, thanks for the report! Unfortunately, we can't fix this problem in Plasma, as it would mean we'd work around Qt's abstraction, defeating the whole point of the locale system abstraction. This is an upstream problem in Qt. As to your question 1.: Yes, you can just change the values in the config file (they will only be overwritten if you use the locale systemsettings module, so don't, and you'll be a happy camper).
