How to change the language in virt-manager?

Does anyone know how to change the default language in virt-manager?

Yes. :wink:

What do you want to do?

What is your system’s language?
Why would you want to start a program with a different language than all the others?

I switched my language on my computer and virt-manager didn’t adapt.

I don’t know how you switched your systems language nor any system details like the Desktop you are using

the generic way is thusly:

locales are defined in /etc/locale.gen
uncomment every one you want (edit as root)
then run
sudo locale-gen

localectl list-locales
will list available locales

localectl set-locale de_DE.UTF-8
will set the german locale
provided it was made available
(use sudo)

if your system is english but you want to start a program (like virt-manager) in german
start it like:
LANG=de_DE.UTF-8 virt-manager

I do that often the other way around to see what the menu items are called in english
LANG=en_US.UTF-8 virt-manager
will start the prgram in english for me

Do I have to restart? It’s not working at the moment.

Languages: Switched from French to English
