Hi Thomas! As Faustin wrote, the directory missing is by itself not an error. Can you please post the command you ran and the error message so we can see what tools/script tries to use this directory and what error message it outputs?
The directory was removed in https://salsa.debian.org/mariadb-team/mariadb-server/-/merge_requests/27 as there has not been any known use of it for a long time.
