Error on installing aircrack-ng "/usr/bin/ld: cannot find -lnl-genl-3"

Question

I am using 14.04. I followed this post on installing Aircrack. As I enter the last command sudo make install I am getting this error:

/usr/bin/ld: cannot find -lnl-genl-3

Answer 1

EDIT

To deal with that particular error install the following packages and try again. Open a terminal and execute the following commands after you cd into the proper directory:

sudo apt-get update
sudo make clean
sudo apt-get install libnl-genl-3-200 libnl-genl-3-dev libnl-idiag-3-dev
make
sudo make install

Short Answer

You don't need to manually download software you need to install silly, this is debian ubuntu not windows :) why do you think we don't have so many viruses and malware like windows does? It's because of certified package management and debian / ubuntu by far has the largest repo of any other unix like distro.

Open a terminal and execute the following commands to install aricrack-ng

sudo apt-get update
sudo apt-get install aircrack-ng

To search for software available through the official ubuntu repositories, you can open the ubuntu software center or you can run the following commands in a similar way described in the following example:

apt-cache search aircrack-ng

or to limit the results to only those containing the word aircrack, use grep like so:

apt-cache search aircrack-ng | grep aircrack
