Hello,

how can I change the language of neon and all applications to for example, spanish?
Neon was installed in english.
I've already went into system-settings -->regional settings and change the languages options there.
But the result is that half the system is now in english and some in spanish.
for example:
-----The launcher categories are in english
-----the sub-categories are in spanish
-----system notifications are in english and some of the "title/headers/description" of those notifications are in spanish
-----konsole messages are in in english.
-----login window actions (shutdown, reboot, suspend, ...) are in english

Well, you get the picture.

help.
thanks.

You should also set the formats, all items except the last one. Are you sure there is a translation team in Spanish.
Restart the system is required.

Hi, @alldeda has pointed out the solution very well.
Could you take a look at the following post?. I also think you have missed something.
https://linuxconfig.org/how-to-change-system-language-on-ubuntu-18-04-bionic-beaver-linux
It is for Gnome Desktop but you could do the same in Plasma KDE desktop.

Thanks for the advice, but I just noticed a big joke. Update plasma to version 5.15.0 has deleted the localization in both my Neon-user edition versions. I set out to USA now, I will no longer use localization. Calculate linux (aka Gento with GUI installer) does not have my localization, I have localized Calculate and I just had problems, one program accepts localization, others do not accept. Neon distro which is the basis of Ubuntu 18.04LTS deletes localization and I have updated plasma from 5.14.5 to 5.15.0.
