This is frst time trying to install Logstash on linux/ubuntu. I keep running into an error that logstash can't start. I have no clue what I did wrong.

I fixed the problem. Embarrasingly, this problem went away after I downloaded logstash.zip and installed. However, logstash.tar.gz still gave me the problem shown above. So my recommendation is to use .zip file download on Ubuntu. ---

An alternative is to use Debian package. [https://www.elastic.co/guide/en/elasticsearch/reference/current/deb.html](https://www.elastic.co/guide/en/elasticsearch/reference/current/deb.html) ---
