I want my locale to be British English (en_GB.UTF-8) and in my
configuration.nix I have
i18n.defaultLocale = "en_GB.UTF-8"; time.timeZone = "Europe/London"
But I’m getting errors like this when I start my shell:
perl: warning: Setting locale failed. perl: warning: Please check that your locale settings: LANGUAGE = "en_GB", LC_ALL = (unset), LC_MEASUREMENT = "en_IO.UTF-8", LC_TIME = "en_GB.UTF-8", LANG = "en_GB.UTF-8" are supported and installed on your system. perl: warning: Falling back to a fallback locale ("en_GB.UTF-8").
What am I missing?
