No worries. :-)

Not quite. Debian's package adheres to the Filesystem Hierarchy
Standard: Data that may be written to does not belong into /usr/.

We don't actually ship a /usr/share/elasticsearch/data directory -- the
data is put into /var/lib/elasticsearch instead. Please check if you
have path.data set in your elasticsearch.yml.
