  Ubuntu is not in the sudoers file problem solving
  Add Date : 2018-11-21      
  In Ubuntu12.04, when using sudo apt-get install XXX, suddenly jumped username is not in the sudoers file problem

Then I check the username of this type, it really is a standard user instead of an administrator user

Solve this problem at least two ways:

one. System Settings -> User Accounts -> Click Unlock -> Enter the root password -> Change AccountType (user type) as the Administrator (Administrator) -> Restart


root user, edit / etc / sudoers permissions to 640 (chmod 640 / etc / sudoers) -> vim / etc / sudoers -> find the root ALL = (ALL: ALL) ALL -> Add

username ALL = (ALL: ALL) ALL -> Modify / etc / sudoers permissions to 440 (chmod 440 / etc / sudoers) -> Restart

In this case the two methods I know, if other methods, please leave a message to announce the great God.
