Outdated, non-existent paths in the language files.

I wanted to see where I could insert the lines. COM_KUNENA_SAMPLE_DATA_QUESTION = “Would you like to install sample data?”
COM_KUNENA_SAMPLEDATA_SKIPPED = ”Installation of sample data skipped”
and found commented out, no longer existing path names in all language files.
The incorrect path names start with “components/com_kunena/views/”, which still existed in Kunena 3.10.12 but no longer exist in Kunena 4.

This is not a problem, these commented out lines are only for orientation.

; JROOT/administrator/components/com_kunena/views/cpanel/tmpl/default.php
In your case, it is this section and you can add the lines at the end of this section.

That's correct. But you can't use it for orientation because this orientation no longer exists.
I think it makes sense to remove these orientation lines completely.
