Important notes

Always install both packages in this order:

1. language independent components (core CU)
2. language-dependent components (language CU)

For language-dependent packages, the language you select does not matter because each package contains updates for all languages.

If you install a new language pack on a SharePoint Server 2019 farm, you must reinstall the language-dependent update afterwards.

Remember to keep Distributed Cache updated as well as SharePoint. See How to update Distributed Cache correctly (in Czech).
