I did reinstall ubuntu 16.04 LTS and try to install ettercap-graphical. everything is going right until I try to consult the dns of ettercap. Normally the etter.dns is in the /usr/share/ettercap directory and that's what I did find: enter image description here
Did etter.dns has another name or other location ? or did I install it the wrong way : sudo apt-get update sudo apt-get install ettercap-graphical ?
