The Prerequisites
Before proceeding with describing the steps in how to update Kali Linux, ensure you meet the following prerequisites:
- A system running Kali Linux (preferably installed on a virtual machine).
- A user account with root or sudo privileges.
How to Update Kali Linux in 4 Steps?
Kali usually uses the Debian Package management system, enabling package updates through the apt (more specifically, the apt-get command). We recommend the following four steps to update Kali Linux on your system.
Step #1: Verify the Source List Files
Before proceeding with updates through the APT package manager, it’s crucial to confirm that your system is linked to the appropriate remote repository. The configuration files /etc/apt/source.list and /etc/apt/source.list.d store the URLs Kali uses to fetch new packages and application updates.
We recommend opening the sources.list file in the terminal to view its contents:
# cat /etc/apt/source.list
You should confirm that the list includes the following URL:
http://http.kali.org/kali kali-rolling main contrib non-free
You should repeat the process for the /etc/apt/source.list.d/ to confirm that the URL is present in the file.
Step #2: Update the System Package Index
Now that you have verified that you have the appropriate URL in the sources file, you can update the local package repository to guarantee that you’re working with the most recent packages.
Execute the following command to fetch the latest package list:
# apt update
Step #3: System Upgrade
It’s time to upgrade your Kali Linux system to ensure you have the latest packages and patches. For this, you can use one of the following commands for this task:
- apt upgrade: This command updates packages without removing any previously installed updates.
- apt full-upgrade: Unlike the previous command, this one not only updates packages but also removes any installed packages if necessary.
- apt dist-upgrade: This command goes beyond the standard package upgrade process by intelligently handling the dependencies, removing obsolete packages, and adding new ones.
We suggest you choose the appropriate command based on your requirements. When you enter the command, you will be asked for confirmation. Press y to confirm and continue the upgrade process.
Step #4: Eliminate Unnecessary Packages
After the upgrade, we strongly recommend freeing up disk space by removing obsolete packages. Run the following command:
# apt autoremove
