How to update Kali Linux step by step Instructions

  1. Configure Kali Linux Repositories
  2. The first step is to set correct Kali Linux repositories. Make sure that your /etc/apt/sources.list file contains the following official Kali repositories:

    deb kali-rolling main non-free contrib
    deb-sources kali-rolling main non-free contrib
    Use only official Kali Linux repositories. Any other listed 3rd-party and unofficial repositories within the /etc/apt/sources.list file may break or compromise your Kali Linux system.
  3. Update Kali Linux
  4. To begin the update of your Kali Linux system first update the packages index list. Open up terminal and enter:

    $ sudo apt update

    Next, optionally, display all packages which are scheduled for update:

    $ apt list --upgradable

    At this stage we have an option to upgrade individual packages using apt install PACKAGE-NAME or upgrade all packages at once:

    $ sudo apt upgrade

    All done. Your Kali Linux system is now fully upgraded.

  5. Upgrade Kept Back Packages
  6. Due to package dependency changes some of the Kali Linux packages might be kept back.

    If this is this case you will be notified by the apt upgrade Linux command at the end of the Kali Linux upgrade process. You may upgrade each kept back package individually using the apt install PACKAGE-NAME command or update all kept back packages at once:

    $ sudo apt dist-upgrade
  7. Uninstall No Longer Required Packages
  8. During your initial system upgrade some of the packages may become obsolete, hence are no longer required. To remove all no longer required Kali Linux packages execute:

    $ sudo apt autoremove
