Convert Debian to Kali

makekali.sh

apt update
apt -y install wget gnupg dirmngr
wget -q -O - https://archive.kali.org/archive-key.asc | gpg --import
gpg --keyserver hkp://keys.gnupg.net --recv-key 44C6513A8E4FB3D30875F758ED444FF07D8D0BF6
echo "deb http://http.kali.org/kali kali-rolling main non-free contrib" >> /etc/apt/sources.list
gpg -a --export ED444FF07D8D0BF6 | sudo apt-key add -
apt update
apt -y upgrade
apt -y dist-upgrade
apt -y autoremove --purge
apt -y install kali-linux-everything

This is dangerous. Why not use Kali?

It's not. I have done it for years. As Kali is based on Debian, but ahead of Debian stable or complementary to Debian testing, there cannot be any trouble.

Even if it are Linux, there can be dangerous.

Explain and develop then.

This way, it's technically a standard APT upgrade process, as it has worked for more than a decade. So, in theory no danger, and in practice no danger (I have done such stuff dozen of times, not a single issue, and always possible to roll back with a bit of apt skills).

i can skip the last part of installing kali for everything right? like download the each tool i need manually.

@TheMadTomato Sure. That's what I do and would recommend by the way : keep it slim with only useful stuff.

For me worked but need to do something more, need to add priority to kali repos cause was giving me unmet dependencies
> sudo nano /etc/apt/preferences.d/kali-preferences.pref

And inside file:

Package: *
Pin: release o=kali
Pin-Priority: 1000

Then worked perfectly !
