Yeah, I have it as well on 4.3.9.
wazuh-dashboard won't install without the -fd option
bash wazuh-install.sh --wazuh-dashboard dashboard -fd -i
with the -fd option, I get the following:
/etc/wazuh-dashboard/opensearch_dashboards.yml contains these 2 lines:
...
#opensearch.username: kibanaserver
#opensearch.password: kibanaserver
...
Even modifying them to match the passwords for kibanaserver in:
tar -O -xvf wazuh-install-files.tar wazuh-install-files/wazuh-passwords.txt
and
systemctl restart wazuh-dashboard
still no joy...
