Problem Description:
Did a clean install of Ubuntu 26.04. Picked ‘Dutch (Belgium)’ as my language in the Installer, selected my keyboard and region.
Upon first launch, various elements on the desktop are still in English (context menus, quick menus in the dock, time format in the top bar, quick menu in the top right corner, …).
Screenshots or Error Messages:
No error messages.
What I’ve Tried:
I’ve tried changing the language in Settings > Region & Language. It only provides ‘Dutch’ as an option; all else seems to be selected correctly.
I’ve tried changing the language using ‘sudo dpkg-reconfigure locales’. Nothing seemed wrong here.
I’ve never had a problem like this in any previous version of Ubuntu, and have no clue what might cause it.
Thanks for pointing me toward a solution. What you suggested didn’t work - it used to in previous versions. So, what I did is, I completely uninstalled the Dutch language packages and reinstalled it. Upon reboot, it now works.
Conclusion is that there might be a bug when selecting a language in the Installer during a clean install. I don’t know if other people have experienced this problem, however.
