Translations by Ahmed Shams

This setting only affects the language your desktop and applications are displayed in. It does not set the system environment, like currency or date format settings. For that, use the settings in the Regional Formats tab. The order of the values displayed here decides which translations to use for your desktop. If translations for the first language are not available, the next one in this list will be tried. The last entry of this list is always "English". Every entry below "English" will be ignored.

This will set the system environment like shown below and will also affect the preferred paper format and other region specific settings. If you want to display the desktop in a different language than this, please select it in the "Language" tab. Hence you should set this to a sensible value for the region in which you are located.

The language support files for your selected language seem to be incomplete. You can install the missing components by clicking on "Run this action now" and follow the instructions. An active internet connection is required. If you would like to do this at a later time, please use Language Support instead (click the icon at the very right of the top bar and select "System Settings... -> Language Support").
