+|RCC| has a know problem with locales, due to changes in glibc 2.27+ which affects
+the local-archive format, which is now incompatible with our used glibc 2.26.
+
 
-|RCC| does not run perfectly on Fedora 23 due to a locale issue. This is a
-known issue under investigation due to the Nix packaging of the product, see the
-`Github issue here`_. |RCC| runs fine on Fedora 21.
+To work around this problem, you need set path to ``$LOCAL_ARCHIVE`` to the
+locale package in older pre glibc 2.27 format, or set `LC_ALL=C` in your enviroment.
+
+To use the pre 2.27 locale-archive fix follow these steps:
 
-To work around this problem, you need to point ``$LOCAL_ARCHIVE`` to the
-workaround locale package.
+1. Download the pre 2.27 locale-archive package
 
-1. Download this package:
-   http://lipa.ms.mff.cuni.cz/~cunav5am/nix/locale-archive
+.. code-block:: bash
+
+    wget https://dls.rhodecode.com/assets/locale-archive
+
 
 2. Point ``$LOCAL_ARCHIVE`` to the locale package.
 
 .. code-block:: bash
 
-    $ export LOCALE_ARCHIVE=/home/VERSION/locale-archive # change to your path
+    $ export LOCALE_ARCHIVE=/home/USER/locale-archive  # change to your path
+
+This can either added in `~/.rccontrol/supervisor/supervisord.ini`
+or in user .bashrc/.zshrc etc, or via a startup script that
+runs `rccontrol self-init`
