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!
