Not quite sure if my problem is connected to this one, as I DO NOT WANT to have anything set to English, neither the system language, nor the country, thus no mixed environment.
However, when I updated my Kubuntu Trusty Tahr (64 bit) with the latest updates from the Kubuntu repositories here on Launchpad and rebooted afterwards, my entire KDE, including all applications, was changed to English all of a sudden! When I opened System Settings -> Locale, I got the following error message: "You have the language with code 'ja' in your list of languages to use for translation but the localization files for it could not be found. The language has been removed from your configuration. If you want to add it again please install the localization files for it and add the language again." Following this, only "American English" was left in the language list on the right. I've then tried to add Japanese again, and while the adding itself seemed to work and it appeared in the list on the right, when I clicked the "Apply" button, I got exactly the same error as above, and Japanese was removed again from the list. I've rebooted after that and tried adding Japanese once more, but nothing changed: the adding itself worked, but clicking on "Apply" once more got me the error message from above, and Japanese was removed again, leaving me with "American English" only. I've also tried manually editing /etc/default/locale - but that didn't do anything. Trying to reinstall the "locales" package in Synaptic got me some error messages: Get:1 http://archive.ubuntu.com/ubuntu/ trusty-updates/main locales all 2.13+git20120306-12.1 [2695 kB] Fetched 2695 kB in 1s (1603 kB/s) perl: warning: Setting locale failed. perl: warning: Please check that your locale settings: LANGUAGE = "en", LC_ALL = "", LC_PAPER = "en_JP.UTF-8", LC_ADDRESS = "en_JP.UTF-8", LC_MONETARY = "en_JP.UTF-8", LC_NUMERIC = "en_JP.UTF-8", LC_TELEPHONE = "en_JP.UTF-8", LC_MESSAGES = "en_JP.UTF-8", LC_COLLATE = "en_JP.UTF-8", LC_IDENTIFICATION = "en_JP.UTF-8", LC_MEASUREMENT = "en_JP.UTF-8", LC_CTYPE = "en_JP.UTF-8", LC_TIME = "en_JP.UTF-8", LC_NAME = "en_JP.UTF-8", LANG = "en_JP.UTF-8" are supported and installed on your system. perl: warning: Falling back to the standard locale ("C"). locale: Cannot set LC_ALL to default locale: No such file or directory (Reading database ... 173420 files and directories currently installed.)

So quite possibly this is a bug in the "locales" package (and possibly somewhere else still.)
