If you’re beating your head against a wall in regards to why some applications seem to fail to parse text correctly (Bazarr) and ultimately complete actions like notifications (Ombi) it may be due to an un-set Language Locale value in your LXC container. Here’s how to fix it:

If you type “locale” and see no value for “LANG” then you have unset values.

1. ssh to your LXC container and run the following (either as root or prefaced with sudo) replacing the language with your preferred language.
2. localectl set-locale LANG=en_US.UTF-8
3. set LC_ALL=en_US.UTF-8
4. locale-gen “en_US.UTF-8”
5. reboot the LXC container

Now if you execute “locale” on the host you should see a new value for “LANG” with your preferred language.
