Installs parrotOS repository and commonly used tools from parrotOS in ubuntu.
By following all steps you will have all tools available in parrot when using apt and be able to update tools with apt update and upgrade.
This script is simply a personal script that installs some default tools like nmap, masscan, etc using parrotOS repository, this is, adds the tools to apt and then apt installs them.
If you want to install all tools that parrotOS has, you should be able to simply do sudo apt-get install parrot-tools-full instead of step 4 (didn't test).
After step 3 you will have all parrot tools in apt, so you can install normally as if you were in parrotOS.
To use this script follow all the steps one by one.
Some downloads will fail when doing step 4, just do step 4 again until all are installed.
This must be done. If you upgrade without doing this, your system will break.
An example of the file /etc/apt/preferences.d/parrot-pinning will be:
Where Parrot has a pin-priority lower than Debian and Ubuntu.
Package: *
Pin: release o=Parrot
Pin-Priority: 500
Package: *
Pin: release o=Debian
Pin-Priority: 700
Package: *
Pin: release o=Kali
Pin-Priority: 50
Package: *
Pin: release o=Ubuntu
Pin-Priority: 1001- Ubuntu 20.04
if you get 404 error codes when trying to dist-upgrade, try to change the mirror in your /etc/apt/sources.list.d/parrot.list to one that has the files.
