So I was following a tutorial to run kismet from virtualbox and I either did not complete all the steps or I followed a wrong set of steps. Now Im unable to use Sudo anymore. This is the error code I receive..please if somebody could help me resolve this. Google hasnt been super helpful. Im unable to just re-install I must fix it. Thank you guys so much for your time.
