[SOLVED] Locales - How do you enable them with no /usr/share/i18n/ directory?

[CashewCaliphate]

I'm trying to run a python script in an ubuntu 16.04 LXC, but it fails with the following message:

This system supports the C.UTF-8 locale which is recommended.
You might be able to resolve your issue by exporting the
following environment variables:

    export LC_ALL=C.UTF-8
    export LANG=C.UTF-8

If I run those two lines in CLI, then the Python script executes fine, but if the LXC restarts, the issue presents itself again. So how do I permanently enable those locales?

The only things I could find online point to supported locales in a /usr/share/i18n/ directory, which doesn't exist in my LXC. And if I just add those two locales to my /etc/locale.gen file, it just labels them as a "bad entry."

So how do I fix this permanently without having to manually export the locales after each reboot?

The locale "C" is special in Unix systems (read more here). Generally speaking, appending /etc/locale.gen followed by a 'locale-gen' is fine.

Regardless, the issue you are seeing is simply because the environment variables (LC_ALL and LANG) are reset every time you enter a new shell (login) - which forcibly happens when you restart the container. Simply put the two "export" lines in a more permanent location (for example at the end of your /etc/profile).

Thanks for the reply.

I added the two export line sin /etc/profile. They show up when I run locale, bit the systemd still fails to start, citing the same missing locales. Is it possible I have to add them in some other manner?

Adding this to the systemd file did the trick!

Environment=LC_ALL=C.UTF-8
Environment=LANG=C.UTF-8
