SSH connection refused and user not in sudoers file

Question

I ran ssh localhost, and got:

ssh :connect to host localhost port 22: Connection refused

Then I tried sudu apt-get install openshh-server, and got:

user is not in the sudoers file .This incident will be reported

Please tell me what should be done further so that an SSH connection is established. I haven't found the solution to my problem in the previous answers. Thank you very much.

Why are you trying to SSH to the same host you're already logged in to? — Philip Whitehouse, Dec 01 '16 at 17:57
actually I need to do that as it is required so that I can install Hadoop afterwards — Umme, Dec 01 '16 at 18:07

Somehow you managed to mangle your group memberships so that you can't run sudo. Answers to this question show how to fix that. Then you can carry on with installing OpenSSH. Good luck!
