Q: I changed the language in KStars, but the interface didn’t update. What should I do?
If KStars does not reflect your selected language, try the following steps:

1. Open a terminal.

2. Run:

   flatpak config --user --set languages "*"
   flatpak --user --reinstall install org.kde.kstars.Debug
   flatpak --user update

3. Restart KStars. (usually closing KStars, will autostart it again)

This forces Flatpak to enable all language packs and refresh KStars. After restarting, the selected language should be applied.

KStars can follow your system language, but you can still set a different language manually. The steps above help ensure all translations are available regardless of your OS language.
