How to update Kali Linux to latest version

In case you have installed Kali Linux using an older ISO, you can easily update all packages doing like this:

# update the installed packages 
john@kali:~$ sudo apt update 
# upgrade kali linux 
john@kali:~$ sudo apt full-upgrade -y

As Kali Linux is continously providing updated packages you might want to do the update every now and then. I usually do that once a week.

Hint | You can shorten the above statements in one line and just type:

john@kali:~$ sudo apt update && apt -y full-upgrade
