Problem with Language and Kubuntu (Dual Boot With CHRX)

Hello.

I installed Kubuntu on my Chromebook with the CHRX partitioning tool, and it installed the system perfectly, Booting Linux and ChromeOS.

The only problem is that it doesn’t let me change the English language and it stays on this screen: (I don’t have any more alternatives and I already installed the language packs)

You need to generate the desired locales.

this is a general Kubuntu question which probably has answers online
