--- Comment #1 from potato4u <eli.we...@gmail.com> --- I had some more time today to investigate the issue: changing the language in the settings doesn't change /etc/locale.conf. If that is intended or not, i do not know. (If not, might be a good option in the future to be able to apply the locale settings to /etc/locale.conf?) the command locale outputs the correct values set by the Region & Language settings. (~/.config/plasma-localerc) Right now i have the following setup: /etc/locale.conf: System Locale: LANG=en_US.UTF-8 VC Keymap: ch X11 Layout: ch X11 Model: pc105 ~/.config/plasma-localerc: [Formats] LANG=en_US.UTF-8 LC_ADDRESS=de_CH.UTF-8 LC_MEASUREMENT=de_CH.UTF-8 LC_MONETARY=de_CH.UTF-8 LC_NAME=de_CH.UTF-8 LC_NUMERIC=de_CH.UTF-8 LC_PAPER=de_CH.UTF-8 LC_TELEPHONE=de_CH.UTF-8 LC_TIME=de_CH.UTF-8 [Translations] LANGUAGE=en_US:de output of command locale: LANG=en_US.UTF-8 LC_CTYPE="en_US.UTF-8" LC_NUMERIC=de_CH.UTF-8 LC_TIME=de_CH.UTF-8 LC_COLLATE="en_US.UTF-8" LC_MONETARY=de_CH.UTF-8 LC_MESSAGES="en_US.UTF-8" LC_PAPER=de_CH.UTF-8 LC_NAME=de_CH.UTF-8 LC_ADDRESS=de_CH.UTF-8 LC_TELEPHONE=de_CH.UTF-8 LC_MEASUREMENT=de_CH.UTF-8 LC_IDENTIFICATION="en_US.UTF-8" LC_ALL= so, in summary, changing the settings in Region & Language works, but the error message: "Could not find the system's available locales using the localectl tool. Please file a bug report about this at https://bugs.kde.org" still persists -- You are receiving this mail because: You are watching all bug changes.
