Kali linux repository install

Kali linux repository install

The topic of repositories is always a large one, and comes up frequently. It is an item which people often get wrong and confused with. Please take the time to read the information below and any references which is linked to before acting on anything.

Default Network Repository Value

On a standard, clean install of Kali Linux, with network access, you should have the following entry present in /etc/apt/sources.list :

[email protected]:~$ grep -v '#' /etc/apt/sources.list | sort -u deb http://http.kali.org/kali kali-rolling main contrib non-free non-free-firmware [email protected]:~$ 

If the output doesn’t exactly match up to the above output, you may not be able to install any new additional packages or receive updates. This may happen for any number of reasons, such as:

You will probably want to read the “switching branches” section to alter this.

Since Kali 2020.3, after Kali’s setup is complete, network repositories will be enabled by default, even if there was no network access during installation.

Switching Kali Main Branch

Kali has two main branches to choose from (please take the time to read which one would be the best option for your setup):

• kali-rolling — default & frequently updated
• kali-last-snapshot — point release so more “stable” & the “safest”

Enabling the kali-rolling branch is done with the command:

[email protected]:~$ echo "deb http://http.kali.org/kali kali-rolling main contrib non-free non-free-firmware" | sudo tee /etc/apt/sources.list 

Enabling the kali-last-snapshot branch is done with the command:

[email protected]:~$ echo "deb http://http.kali.org/kali kali-last-snapshot main contrib non-free non-free-firmware" | sudo tee /etc/apt/sources.list 

Note that such a change is effective only after running sudo apt update .

Enabling Kali Additional Branches

Kali also proposes additional branches for special cases. In theory, it’s possible to enable those regardless of the main branch you use. In practice though, they are meant to be used in addition to kali-rolling . We discourage using it in addition to kali-last-snapshot unless you know exactly what you’re doing. Those additional branches are:

• kali-experimental — packages which are under testing or work in progress
• kali-bleeding-edge — packages automatically updated from upstream git repositories

Enabling or disabling those branches is best done using the command-line tool kali-tweaks , under the Network Repositories section:

If you prefer, you can also enable those branches manually from the command-line. For example, enabling kali-experimental is done with the command:

[email protected]:~$ echo "deb http://http.kali.org/kali kali-experimental main contrib non-free non-free-firmware" | sudo tee /etc/apt/sources.list.d/kali-experimental.list 

Note that in the command above, we don’t modify the file /etc/apt/sources.list , but instead we create a new file /etc/apt/sources.list.d/kali-experimental.list . This is a convention: the file /etc/apt/sources.list should only contain the main branch, while additional branches should go in /etc/apt/sources.list.d/ , one branch per file.

If you follow this convention, then disabling the kali-experimental branch is straightforward:

[email protected]:~$ sudo rm /etc/apt/sources.list.d/kali-experimental.list 

The branch kali-bleeding-edge can be enabled with a similar command, we just need to change the name of the branch:

[email protected]:~$ echo "deb http://http.kali.org/kali kali-bleeding-edge main contrib non-free non-free-firmware" | sudo tee /etc/apt/sources.list.d/kali-bleeding-edge.list 

To disable kali-bleeding-edge :

[email protected]:~$ sudo rm /etc/apt/sources.list.d/kali-bleeding-edge.list 

Sources.list Format

• Archive is going to be deb (Regular Binary) or deb-src (Source), depending if you want a package or the source of the package.
• Mirror should be http://http.kali.org/kali as this is our load balancer, which will direct you to best mirror.
• Branch is what version of Kali you wish to use.
• Components are what packages you wish to use, based on the Debian Free Software Guidelines (DFSG). Kali defaults to everything.

Default Offline Install Values

During the Kali setup process, if you don’t have access to a network connection to reach a repository, you will perform an offline installation of Kali Linux. You will be limited to the packages & the version which is on the medium you installed Kali from. This will then configure Kali to continue to use this medium to install packages from, even after Kali has been installed.

This means you will not get any updates to packages, or any new additional tools, which can be frustrating. You can see if you the offline media enabled if your values match up with what’s below (or if you want to enable this option):

[email protected]:~$ cat /etc/apt/sources.list # # deb cdrom:[Kali GNU/Linux 2020.1a _Kali-last-snapshot_ - Official amd64 DVD Binary-1 with firmware 20200213-14:56]/ kali-rolling main non-free #deb cdrom:[Kali GNU/Linux 2020.1a _Kali-last-snapshot_ - Official amd64 DVD Binary-1 with firmware 20200213-14:56]/ kali-rolling main non-free # This system was installed using small removable media # (e.g. netinst, live or single CD). The matching "deb cdrom" # entries were disabled at the end of the installation process. # For information about how to configure apt package sources, # see the sources.list(5) manual. [email protected]:~$ [email protected]:~$ sudo apt-cdrom add Using CD-ROM mount point /media/cdrom/ Identifying. [ea19ff4bedaa6c8f4662c0e8c58ed44c-2] Scanning disc for index files. Found 2 package indexes, 0 source indexes, 0 translation indexes and 0 signatures This disc is called: 'Kali GNU/Linux 2020.1a _Kali-last-snapshot_ - Official amd64 DVD Binary-1 with firmware 20200213-14:56' Reading Package Indexes. Done Writing new source list Source list entries for this disc are: deb cdrom:[Kali GNU/Linux 2020.1a _Kali-last-snapshot_ - Official amd64 DVD Binary-1 with firmware 20200213-14:56]/ kali-rolling main non-free Repeat this process for the rest of the CDs in your set. [email protected]:~$ 

If your output matches what’s above, please see the switching branch section, if you wish to receive updates.

However, if you do have network connection, which has access to network repositories, it will be enabled for you. You don’t need to do anything.

Non-Kali Repositories

If you want to install additional tools and software (such as signal) outside of what Kali has to offer, you may need to include an extra repository for this to happen. Please do not alter /etc/apt/sources.list , as this is used for the Kali Linux Operating System. Any extra tools and software needs to be placed into their own file in the directory /etc/apt/sources.list.d/ (such as /etc/apt/sources.list.d/repo-name.list , replacing repo-name with the mirror name). It is highly recommended that each mirror should be in its own file.

By adding Kali’s repository to a non-Kali OS (such as trying to add Kali to Ubuntu), this will highly increase the chance of your system not working. It may not happen straight away, but without any warning, it may break. We will not be able to offer support (and based on what we have seen over the years, most other OS will not help too).

Likewise, adding other operating system’s repositories into Kali (such as trying to put Ubuntu on Kali), will break your installation. This is the single most common reason why Kali Linux systems break.

If any guides are telling you to do anything else than the above, this is unofficial advice, and completely not supported by Kali Linux. More often than not, users in this case end up doing a reinstall after learning this lesson.

Mirrors

We have a list of official Kali Linux mirrors, as well as a guide on how to setup your own. This may be kept as a local repository which is only accessible on a LAN, or a remote private one, or if you have the ability to, you may wish to share back to the community and make it public allowing for anyone else in your geographical area to benefit from it.

Source Repositories

By using a deb in the repositories, it will allow for binary packages to be downloaded. However, should you require the source to a package (so you can compile the package yourself if you so wish, or look into debugging a problem with a package), you can add deb-src as a extra line in the repositories:

[email protected]:~$ echo "deb-src http://http.kali.org/kali kali-rolling main contrib non-free non-free-firmware" | sudo tee -a /etc/apt/sources.list 

We used kali-rolling for the branch above, but you can select any value you wish.

Step-by-Step Guide: Adding Repositories to Kali Linux for Expanded Software Options

The repository is a big topic and I can’t cover everything in one article. So today I am just going to explain about the Kali Linux repository.

You can add the Kali Linux repository after following simple steps.

What is Repository in Linux

In simple words, a Repository is a storage location, Where all the packages are stored.

Packages refer to tools, utilities, or software that you may install on your Linux system including Kali Linux.

All the packages available on the Kali Linux repository are tested, maintained, and maintained by its developers and managers.

If you will download and install packages on Kali Linux in the future from the repository, it will work fine. because it has been tested by Kali developers.

You will not face any type of problem or crash in your system when you get packages from the repository.

In other words, you can not trust other resources for getting packages/tools.

You are on the client-side, So an apt apt-get package manager helps to install the new and latest packages on your system and update the repositories.

How to Add Kali Linux repository for Beginners

As you know, at the time of updates and upgrades Kali Linux, the apt or apt-get package manager checks only the application stored on its own data repository.

This is good for you and other Kali users, Some updates and upgrades could make Kali Linux nonfunctional, all software is tested by the Kali developers before adding the Kali Linux repository.

There is some third-party application that is not available on the Kali repository, in this case, additional repositories may be needed to be added.

There are simple steps to configure the Kali Linux repository on your system. Follow the given two steps:

Step 1: Use leafpad or another text editor to open and edit /etc/apt/sources.list.

Step 2: Add the following code to the file and save the file. You can add the following anywhere in the file.

Just copy the following code and paste it into the file.

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

Step 3: Verify the updated file:

You can use cat command to verify the updated file. You can you have added code properly inside a file or not

Updating Kali Linux

Like other operating systems, Kali has the implicit capability to update both the operating systems and the software, or packages, installed. As upgrades to the package get accessible, they will be presented in the Kali store. This store can then be checked to guarantee the operating systems and provisions are up to date. Upgrades are typically more small fixes that address software bugs, or errors, or are utilized to include new fittings competencies. Use the following commands to update the system :
#apt-get update

Upgrading Kali Linux

Like updating, upgrading Kali can likewise be carried out at the command line with the pt-get utility. Upgrades are regularly significant updates to requisitions or the working framework itself. Updates offer new usefulness and are much bigger than upgrades ordinarily obliging more of a chance and space on the System drive.
