Kali Linux

[tllim]

if you know the software name you can install  , you don't need to use kali linux , kali linux base on ubuntu

dam, yep you are absolutely right 

I forgot about that option! Thanks a lot! 

sorry , kali linux is base on debian

Yep but Ubuntu is based on Debian too, so your statement is still true

While Ubuntu is a fork of Debian, it has diverged sufficiently that most Linux developers consider it a separate OS.  The fact that both use apt-get and related for package maintenance doesn't change the fact that, while some software packages from one distro can be used in the other distro, many will not - and the problem seems more severe when trying to add a Debian package to an Ubuntu install.

Ubuntu's focus is toward a more cutting edge software base, while Debian (like Slackware) is oriented toward stability and security, with little concern for releasing new versions until they've been thoroughly tested.  Hence, Debian's current stable, jessie, is v8.X and Slackware sits at v14.1, compared to, what, v15.10 for Ubuntu?  This, despite the fact that Slack and Debian are the two oldest actively maintained distros, dating back to the earliest days of Linux.

Kali, like Ubuntu, was originally forked from Debian (not Ubuntu), but has since grown apart in a fashion similar to Ubuntu.  It has, so far, maintained enough continuity that the majority of Debian's .debs are still compatible.  Several Linux devs/sysadmins have told me that, though the Kali team initially considered Ubuntu as their base distro, they quickly determined that it was too buggy and too insecure, so chose Debian-testing instead.

Both Debian and Slackware offer ARM versions, and vast software repositories, with large dev teams backing them.  I intend to explore their resources before those of Ubuntu.

Appreciate and thanks on the good Linux distro explanation.
