SharePoint Server 2019 CU – CU download link:

After installation, remember to run the SharePoint 2019 configuration wizard (SharePoint 2019 Products Configuration Wizard), or the following command:
PSConfig.exe -cmd upgrade -inplace b2b -wait -cmd applicationcontent -install -cmd installfeatures -cmd secureresources -cmd services -install

Important

Always install both packages in this order:

  1. language independent (updates language-independent components)
  2. language dependent (updates language-dependent components)

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

If you install a new language pack on a SharePoint Server 2019 farm, you must subsequently reinstall the language-dependent package (language dependent).

Remember that, in addition to SharePoint, the Distributed Cache service must also be updated; see How to update Distributed Cache correctly and, for Office Online Server, you must have the current RTM version; see  How to update Office Online Server.
