How to install language support completely using command line?

After a fresh ubuntu/lubuntu/xubuntu install, if you go to language support, you'll get the message prompt "language support is not installed completely", to install the language support.

How do you trigger the installation of language support using bash command line? In a way to automate post-installation further.

note: not sure if this only happens if you have extra languages/locales in ubuntu, but since I'm not anglo, it probably has.

sudo apt install $(check-language-support)

That should make the Language Support prompt shut up. :) It may install both some English and non-English packages
