如何在KaliPi上安装Ettercap

This is for my Ethical Hacking and Countermeasures class; I am doing a project using a raspberry pi running Kali Linux, but the distro I downloaded does not have ettercap installed. I have already tried sudo apt-get install ettercap, along with a bunch of other ways to install that I found online. Does anyone know how I can get ettercap onto my kalipi?This is for my Ethical Hacking and Countermeasu
