Problem ubuntu@(none):~$ sudo true sudo: unable to resolve host (none) Two things to check (assuming your machine is called  my-machine , you can change this as appropriate): That the  /etc/hostname  file contains just the name of the machine. That  /etc/hosts  has an entry for  localhost . It should have something like: 127.0.0.1 localhost.localdomain localhost 127.0.1.1 my-machine If either of these files aren't correct (since you can't sudo), you may have to reboot the machine into recovery mode and make the modifications, then reboot to your usual environment. Example Your hostname ( dave00-G31M-ES2L ) is not represented in  /etc/hosts . Add an  L  to this line: 127.0.1.1 dave00-G31M-ES2 So it becomes: 127.0.1.1 dave00-G31M-ES2L In order to accomplish this, open a console (press  Ctrl + Alt + T ) and type: sudo gedit /etc/hosts Add the letter  L  as mentioned, save and exit.
