As the title states ettercap has disappeared on me, I don't know if i installed a package that stripped it away or whats going on but when I tried to download it from the repos again I get a 404 error

E: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing?
I did run apt-get update and then I tried apt-get install ettercap --fix-missing and still got the 404 error.

I noticed this same problem has been occurring with other people in the update-script thread, but I've personally never used that script.

Does this have anything to do with the latest version of ettercap being released?
