I have been unable to install a number of applications including anaconda and druid on my ubuntu 16.04 system because whenever they try to open a url using localhost it flashes a message: urlopen error [Errno 111] Connection refused

I am unable to even use curl as whenever I try something like,

curl -X OST' -H 'Content-Type:application/json' -d @quickstart/tutorial/wikipedia-index.json http://localhost:8090/druid/indexer/v1/task

It flashes the message: curl: (7) Failed to connect to localhost port 8090: Connection refused

As this problem has propagated across multiple applications I think there is some problem with my localhost and ports connection. I really need help, I'm not able to do anything on ubuntu!

It means 8090 port is not available yet, maybe any service running on it. you can resolve this error by changing port in overlord/runtime.properties. You can add this.
