  • If you aren't a sudoer, I guess you either screwed up your root access or you are not supposed to perform administrative tasks on this system. – s3lph May 1 '15 at 14:24
  • It doesn't ask for "PASSWORD FOR ROOT", but rather for "password for deepak". Do you own the machine? – mikewhatever May 1 '15 at 14:27

    Ask your admin to fix this ;) – Rinzwind May 1 '15 at 14:30
  • Add the output of groups and id commands. – muru May 1 '15 at 14:32

If it's your computer and if you are only one user, the password should be the same as login password. Otherwise it will be predefined password either from another user or Ubuntu

  • i entered same password,but it showed it as error – Deepak Ramanan May 1 '15 at 14:31

    That's the right password: deepak is not in the sudoers file. This incident will be reported. -1 – A.B. May 1 '15 at 15:13
