If you get errors/warnings like
Code: Select all
perl: warning: Setting locale failed.
perl: warning: Please check that your locale settings:
LANGUAGE = "",
LC_ALL = (unset),
LC_TIME = "sr_RS.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").
you should run sudo dpkg-reconfigure locales
In my experience it's best to select en_GB.UTF-8, en_US.UTF-8, and sl_SI.UTF-8 (sr_RS in your case). Set en_GB as your default locale. Reboot.
In System Settings I have two languages en_GB (default) and en_US. Additional formats are all sl_SI except for region which is en_GB
And I have only Slovenian keyboard layout.
Also check /etc/default/locales if there are settings for locales not installed
