How to Update Kali Linux?

Kali uses the Debian Parcel management system, which allows you to update and upgrade using the apt or apt-get command. Follow the steps outlined below to update and upgrade Kali.

Step 1: Cheque the Source List Files

When downloading updates using the APT packet director, ensure the organization is connecting to the correct remote repository. Configuration files /etc/apt/source.listing and /etc/apt/source.list.d/ incorporate URLs from which Kali installs packages and applications.

Open the configuration files to check the source:

          cat /etc/apt/source.list        

The output should display the URL deb http://http.kali.org/kali kali-rolling main contrib non-free as in the image below.

The aforementioned applies for files inside /etc/apt/source.list.d/.

Step 2: Update Packet Managing director

Before installing the latest software, you need to update the parcel repository to ensure yous are downloading the newest versions. Run the following control to go the latest parcel lists:

          apt update        

Notation: Kali had a default root user on versions up to 2020.1. Since more than and more users started running Kali every bit their day-to-twenty-four hour period operating arrangement, they decided to motility to the traditional security model of having a not-root user. The default password for the root user is toor. If you are not logged in every bit the root, make sure to add the Linux sudo control prefix.

• The apt full-upgrade command downloads and updates packages. However, it also removes already installed packages if needed.
• The apt dist-upgrade command does the same as a regular upgrade while intelligently handling changing dependencies, removing obsolete packages, and adding new ones.

Once y'all determine how to upgrade, type in the command and press Enter. The system will ask you to confirm the installation - type yes or y and press Enter to exercise so.

Annotation: Instead of running each command separately, you tin update Kali Linux using a single command: apt update && apt upgrade .

Step 4: Remove Unnecessary Packages

Remove obsolete packages left later the upgrade to free up disk space by running the command:

          apt autoremove
