Come back repository !

I'm so "sick in my head" when 3 days have not conclusion, but right now I have idea why my package didn't install with another packages. And finally that my repository in source list broken. There are some syntax command line interface to fix it :

1. Open command list interface that's terminal in your linux system,
2. Typing this syntax sudo mv /etc/apt/sources.list /etc/apt/sources.list.old
3.  Then typing again gksudo gedit /etc/apt/sources.list
4. Fill the source list with repository(es).

There are many repositories on linux system, but for penetration and distribution system I had have recommended for you :

deb http://kambing.ui.ac.id/ubuntu oneiric main restricted universe multiverse deb-src http://kambing.ui.ac.id/ubuntu oneiric main restricted universe multiverse
