Please format your code, logs or configuration files using `` icon as explained in [this guide](https://discuss.elastic.co/t/about-the-elasticsearch-category/21) and not the citation button.

Some thoughts: - You should not be connected as root but as `elasticsearch` user. - The [documentation](https://www.elastic.co/guide/en/elasticsearch/plugins/current/installation.html) says to run: ```auto sudo bin/elasticsearch-plugin install ingest-user-agent ``` May be you did not follow from the start how to properly install elasticsearch? Which package did you install? --- _[View the full topic](https://discuss.elastic.co/t/unable-to-start-elasticsearch-java-lang-illegalstateexception-duplicate-key-org-elasticsearch-plugins-pluginsservice-bundle-e3623fe/170847)._
