I'm trying to install the ELK stack on a fresh Ubuntu 18.04 server. Elasticsearch and kibana are now working and I've moved onto Logstash but i get the following error when trying to install using apt. I am following the installation guide for deb files on the main [elastic.io](http://elastic.io) site. After this operation, 294 MB of additional disk space will be used.

Thanks - that got me on the path. I changed to version 8 OpenJDK and then I had to change the /etc/logstash/startup.options file to reflect that: # Override Java location JAVACMD=/usr/bin/java I then ran the sudo /usr/share/logstash/bin/system-install to update the install script as advised in startup.options. This threw up another error ( on bother!) which was that /etc/default/logstash was a directory - huh? I removed it and re-ran the /usr/share/logstash/bin/system-install script and it completed without errors. I now have a working ELK stack. ---
