I am running on Ubuntu 20 04. I have LibreOffice 6.4.4.2 installed and trying to switch its user interface to Czech language.
I have installed the package libreoffice-l10n-cs
and restarted LibreOffice.
When I click on Tools -> Options -> Language Settings -> Languages, "User Interface" is set to "Default - English (USA)". When I expand the select, "Czech" is not listed in the options.
There are other questions about language support in LibreOffice on Ask Ubuntu, like
how to change LibreOffice UI's language?
Marathi localization does not activate at start-up for libre office
but they did not help me to switch Libre Office to Czech.
What am I doing wrong?
UPDATE
The commands suggested by N0rbert produce the following output:
