Proper Installation of Kali linux tools in Ubuntu

I think everyone has known - we need to install katoolin to use Kali Linux Tools on Ubuntu. Before did anything I had looked through the internet and also found out these solutions: Can I install Kali tools on Ubuntu, How to Auto Install All Kali Linux

So here are my steps:

apt-get install git
git clone https://github.com/LionSec/katoolin.git && cp katoolin/katoolin.py /usr/bin/katoolin
chmod +x  /usr/bin/katoolin
sudo katoolin

Then, to add Kali Linux repositories and update them, I selected option 1 from the katoolin Menu

Then, to view the available categories and install all available tools, I selected option 2 from the main menu of katoolin and then pressed 0.

But after that I got this:

What do you want to do ?>  

1) Add Kali repositories & Update 
2) View Categories
3) Install classicmenu indicator
4) Install Kali menu
5) Help

Furthermore, I got an error in Software Updater - it didn't let me do anything. Ubuntu just hung up. I solved this problem by deleting kali linux repositories in katoolin and then in Software Updater.

Does anyone know how to install Kali Linux tools in Ubuntu 16.04 in a proper way?

Introduction

Katoolin is a collection of scripts for automating the installation of Kali linux tools in different platforms other than Kali linux, and installing Kali linux tools with Katoolin in other OSs or Windows Subsystem for Linux is always less secure than installing the same tools in Kali Linux. Kali Linux is named after the Hindu goddess of destruction which should give the user some indication that even Kali Linux itself is risky and difficult to manage, especially for new users.

Katoolin draws its tools from a variety of sources including apt and GitHub. Katoolin doesn't know anything about the platform that it is running on, so the safest way to use Katoolin is to install each tool the hard way one tool at a time, checking each time to see if that tool is included in the default Ubuntu repositories and if so installing it that way instead. When the installation is finished, the software sources that were added by Katoolin should be immediately disabled in order to prevent Katoolin from replacing packages that were installed from the default Ubuntu repositories with its own updated packages whenever Ubuntu software is updated.

Installation of Kali linux tools

(Re)install Katoolin as follows:

1. Open the terminal and type:

   sudo apt install git  
   git clone https://github.com/LionSec/katoolin.git && sudo cp katoolin/katoolin.py /usr/bin/katoolin  
   

2. Make /usr/bin/katoolin executable.

   sudo chmod +x /usr/bin/katoolin  
   

3. Run Katoolin as follows and you will see the Katoolin interface:

   cd /usr/bin/
   sudo ./katoolin   
   

   
   ^{View the categories of available software in katoolin interface}

Press 0 to install all Kali linux tools.

When you go to View Categories and then enter 0 for all, the installer will immediately return to where you were. Scroll up, and you'll see that a number of the packages can't be found. Those packages are no longer maintained or have been removed from the Kali repositories. Even with this issue, you'll still find a lot of the Kali software available for installation.

So the best option is to install Kali linux tools in a series of distinct steps. Just like if you want to install Forensic tools on your system, then choose its option from the category and then type 0 to install all forensics tools. If this still doesn't work, then you have to install whatever forensic tools that can be installed one package at a time.

This is why the Katoolin interface sometimes hangs when you try to install all of the Kali linux tools at once. Take the time of waiting for the server to respond to a request for a package that is not available and multiply it by how many unavailable Kali linux tools there are in the Katoolin repositories.

If you wish to go back to the main menu, type gohome in your katoolin interface. Now select the option 3 or 4 to install either the classicmenu indicator or the Kali menu. Press the y key to continue and then press Enter to start its setup.

Once you are done with installation of Kali tools using katoolin, you can quit by pressing the keyboard combination Ctrl+C and you will see the goodbye message.

shutdown requested....Goodbye...

Warning about updates after installing Kali linux tools

The LionSec Katoolin GitHub webpage clearly warns Katoolin users to be careful when updating software.

Before updating your system, please remove all Kali-linux repositories to avoid any kind of problem.

After using katoolin and adding the repositories , its safe to run sudo apt-get update, but do not use apt-get upgrade if you do, your gnome and desktop will fail to start.

In katoolin :

1. Add kali repositories & Update

2. Update your apt-get by katoolin or your terminal

Install all the tools you want, after that do the cleaning by removing kali repos from your sources.list and apt-key.

If any error occurs, it comes from the sources.list, meaning the package or tool is not designed/available for your Linux architecture or katoolin itself has to be updated, because repositories were changed by the owner.

Advice:

1. Keep in touch with katoolin developers.

2. Install aptitude:

   sudo apt-get install aptitude
   

   then do a search for the requirements of the package candidates, for example:

   aptitude search "?provides(wine)"
   

   read more about aptitude: What is the difference between dpkg and aptitude/apt-get?

3. Read about the difference between unable to locate package & no candidates: What does Package <package> has no installation candidate mean?
