ADDITIONAL INFORMATION
Comment 1 Nico Tolvanen 2024-04-23 23:22:00 UTC 
I can also confirm this issue even with kde 6.0.3 in fedora 40. However I can't change the locale in settings at all.
Comment 2 Graeme Murray 2024-04-27 21:54:44 UTC 
I have the same problem, Fedora 40 kde 6.0.4
Comment 3 muso.am 2024-05-20 19:11:41 UTC 
Same problem, Fedora 40 KDE 6.0.4
Comment 4 hanyoung 2024-05-21 15:03:13 UTC 
Confirmed, localectl executable is not installed by default on fedora 40, despite the doc still mentions it: https://docs.fedoraproject.org/en-US/fedora/latest/system-administrators-guide/basic-system-configuration/System_Locale_and_Keyboard_Configuration/#System_Locale_and_Keyboard_Configuration.adoc#tab-locale_options

Maybe an upstream bug? Because it does present in older versions of fedora.

That's not true, /usr/bin/localectl is installed by default and is part of systemd package which is in base install. I have fedora 40 kde spin installed and I can confirm I can run localectl and still have the same error message when trying to change language in KDE's configuration UI.
Comment 7 hanyoung 2024-07-27 10:11:06 UTC 
It seems like fedora doesn't build plasma-workspace with GLIBC_LOCALE_PREGENERATED enabled, I've filed a bug in fedora.
