My pwd doesn't contain any colon. I literally just downloaded and unzipped the latest logstash, installed the JDK as requested, and tried to run an example.
I'm following https://www.elastic.co/blog/getting-started-with-hosted-elasticsearch-v5-and-a-sample-dataset, which clearly a bit dodgy since the git repo it says to use the conf from indicated that's a legacy conf.
But I'm not getting that far. Why won't a clean install of logstash run at all, please?
