Common Steps to Update Kali Linux

Let us discuss the two most commonly used steps to update Kali.

Configure Kali Linux Repositories

First step is about configuring Kali Linux repositories. You have to set accurate Kali Linux repositories here where you need to first make sure that sources.list file is having below-mentioned official kali repositories. This sources.list can be found under etc/apt.

deb https://http://kali.org/kali kali-rolling main non-free contrib

How to Update Kali Linux Repository

Here, we are going to discuss update Kali Linux’s network repositories. 

  1. Before you start, please don’t forget to take machine’s backup. You should also set it up on latest version. Do this by below-mentioned command.

sudo apt-get update

  1. Now, you can upgrade the downloaded update (from previous command) by:

sudo apt-get upgrade

  1. Now, you are ready to start inputting or updating the repositories
  2. First make sure that you are having all the files where you will be adding/deleting/modifying repositories. This is only required if you are performing fresh Kali Linux installation.
  3. You can find these files by simple below-mentioned command 

sudo -i

  1. The command mentioned above will be having all admin and root user rights. You should open the file containing standard repositories

leafpad /etc/apt/sources.list

  1. After that, file be opened with standard repositories. 

“deb-src http://http://kali.org/kali kali-rolling main non-free contrib”

“deb http://http://kali.org/kali kali-rolling main non-free contrib”

“deb-src http://http://kali.org/kali kali-last-snapshot main non-free contrib”

“deb-src http://http://kali.org/kali kali-experimental main non-free contrib”

  1. After you find them all (from step 8), you can leave them as they are.  Below that, you can add new repositories. You can also delete all of them and put new (it’s up to you)

How to Update Kali Linux in VMware

No doubt, it is recommended to perform updates if new version releases. This is because the new versions always comprise of new features, better performance, fast results, enhanced security, and necessary improvements. As we already know that Kali Linux can be updated to latest version through Terminal. You better should take necessary backups before making any updates. 

If you are using Kali on VMware virtualization program, you can have a new snapshot for better system backups. let us discuss in this piece of content about updating steps for Kali Linux on VMware machines.

Let us have a quick look on the steps below.

Step 1 – Find Current System Version

This is for sure the first step where you at first take complete backup. After that, you run Kali OS and turn on the terminal on the desktop.

You should first find current system version. This can be accomplished by using the following command:

cat /etc/os-release

Step 2 – Check Your Repository List

After finishing previous step, you can now check your repository list. This is a PRE-REQUISITE and system update can’t really take place without completing this step.

You need to run the below-mentioned command to make things work.

cat /etc/apt/sources.list

The above-mentioned command will provide you with all addresses, which are not having # character. There can be a possibility where no repository address is present. For this purpose, you need to run the following command where you can open and edit Kali Sources List manually by yourself.

nano /etc/apt/sources.list

You can now add customized below-given address to your sources list and then press CTRL+X / Y / Enter for saving the same.

deb https://http://kali.org/kali kali-rolling main non-free contrib

Step 3 – Update Application Packs

After repository configuration, run this command.

apt-get update

This command will not update system versions but brings only packages and applications currently installed on the system. Simply, it checks and saves new versions (if there are any).

Step 4 – Update LINUX

When the new version for Linux is released, it provides users with the best experience including major bug-fixes, enhanced security, and updated applications. For updating Linux, run the same command mentioned in previous step on terminal. 

If you want full system upgrades, you can use full-upgrade command on the terminal.

After verifying the smooth internet connection, you can update Kali Linux by using below command.

apt-get update && apt-get -y full-upgrade

apt-get upgrade actually updates entire system to new one but full-upgrade command performs system upgrades to latest beta versions.

Step 5 – System Reboot

After you are done installing latest Kali Linux version, you should now reboot the system. You need to run the following command for rebooting purposes.

shutdown -r now

This will reboot your system and verify Kali version after restarting.

How to Update Kali Linux by Live USB Method

Kali Linux “LIVE” provides users with the two best options. First includes data preservation on Kali LIVE USB and other across Kali Live reboots. This is really beneficial in most of the cases and helps retaining documents and data, keep testing results and configurations safe. When running Kali “Live”  from USB even across different systems, it works like a charm.

Data is stored on USB, which can be made encrypted too.

Let  us assume you are the root user and user USB drive is /dev/sdb. Moreover, your USB capacity is 8 GB minimum where Kali takes 3 GB space and 4 GB empty partition will be created to preserve data.

The system lets us create new partition and puts ext3 FS on it creating a persistence.conf file on new one.

  1. First step you have to follow is about imaging the Kali Linux ISO to USB
  2. Secondly, Let’s assume the partition names as sdb1 and sdb2. You can check partitions by the command fdisk -l.

It is better if you create and format any additional partitions on USB. First, create new one in empty space above Kali partitions. This will be done by using the command gparted, which will read ISO. You need to shrink that block to only adjust itself for Kali Live partition.

end=7GiB

read start_ < <(du -bcm kali-linux-2020.3-live-amd64.iso | tail -1); echo $start 

parted /dev/sdb mkpart primary ${start}MiB $end

 

The command above will advice you that exact start value can’t be used. When parted is done, new partition will exist in sdb3 and can be verified using fdisk.

  1. Thirdly, you have to create ext3 file system and name it as persistence

You can create mount point where you can mount new partition and then you can make configuration file for enabling persistence. After that, you can unmount the partition.

Commands are:

mkdir -p /mnt/my_usb

mount /dev/sdb3 /mnt/my_usb

echo “/ union” > /mt/my_usb/persistence.conf

unmount /dev/sdb3

In this step, you can also apply LUKS encryption if needed. You will get warning about data i.e. it will be overridden.  You can type Yes if you really are sure about that. You can enter now your selected paraphrase and remember it for future use. If you forget this, your  data will remain persistent but unusable

  1. Fourthly, you can now close encrypted channels

Apply the following.

cryptsetup luksClose /dev/mapper/my_usb

That is it. You can now plug your USB to have persistent features and can bootup Kali Live. Just make sure that your BIOS settings are set to boot from USB mode to make things work.

When kali Linux screen appears, you should choose persistent option, which you have setup on USB wither normal or encrypted.

We have discussed the ways we can up[date Kali Linux but these are not limited. It is up to you how you make the best use of OS. Kali Linux is used by various businessmen worldwide and provides lots of features to the valuable users. It provides ext3 extension and there is no exe file virus issues in the same too.

All You Need To Know About Kali Linux Update Single Line Command

Kali Linux and Ubuntu are Debian based. This means that the two are more similar. Both Kali Linux and Ubuntu use Debian’s package management system ‘apt.’

You can only use the apt command whenever you want to install, uninstall, or update packages such as your system software. This certifies apt command to be named a package manager.

Back to our case, we combined two commands using the ‘&&’ option and ‘update’ and ‘upgrade.’ Using these options will leave many confused thus, there is a need to explain it into detail. Here are what you need to know:

apt update

This command will only refresh all the repositories available in your system. The check will be mainly to target any available new package from Kali Linux servers. It would be best if you kept in mind that this command neither installs nor updates any available package but only finds the information about the packages.

apt upgrade

This is the command that will update your system. Immediately you will run this command in your computer, and your system will begin downloading package updates. Upon completion, it will then upgrade them to their latest versions.

apt update && apt upgrade –y

Using the ‘&&’ will save you the time from typing the commands after another. The commands will run automatically when the first command completes.

Are you mind-boggling on why the ‘-y’ option was used? Using the ‘-y’ option also saves you the time of hitting the Enter button after typing the commands. ‘-y’ stands for yes hence no need of pressing the enter key.

Conclusion

What are you waiting for? Open your terminal and type the mentioned single line command, and you are good to go! The new features are worth the update. Update your Kali Linux today! Good luck!
