What were you trying to do that didn't work?

When I change the system-wide locale using Settings → Region & Language, the expected system locale (e.g., LANG= value in /etc/locale.conf) is not updated with only one user on the system.

What is the impact of this issue to you?

The system-wide locale remains unchanged, and the desktop interface still appears in the old locale despite selecting a new one.

Please provide the package NVR for which the bug is seen:

gnome-control-center-40.0-43.el9.x86_64

systemd-252-59.el9.x86_64

glibc-common-2.34-242.el9.x86_64

How reproducible is this bug?:

Always

Steps to reproduce

1. Install Rhel-9.8
2. Open Settings, navigate to Region & Language.
3. Under Language, select a new locale (e.g., change from English (en_US) to Japanese(ja_JP)
4. Log out and log back in, or reboot.
5. Run the following commands in the terminal:
6. **

   $ localectl status
   $ cat /etc/locale.conf

   **

Expected results

Changing the locale in Settings → Region & Language should update /etc/locale.conf and running localectl status should show the new locale and system locale should be updated , when only one user is present on the system.

Actual results

Locale change is not applied system-wide and the UI stays in the old locale.
