Hello
Aleksandra Błaszczyk,
I tried installing and got the same error. It looks like the package is missing.
However, I used this command and got it working:
/usr/share/wazuh-dashboard/bin/opensearch-dashboards-plugin install anomalyDetectionDashboards --allow-root
Restart the Wazuh dashboard to effect the changes:
systemctl restart wazuh-dashboard
Hope you find this information helpful.
