Change the time and she changed the something wrong with this sudo really fz. Frog holding this error message, the google, and found two solution.
First, not yellow, very violent, with root privileges to delete the / var / run / sudo directory.
The second, run sudo-k, this command is used to remove the sudo timestamp, next time you run sudo, it will tell you want to password.
