Get the latest unreleased features and bug fixes with Kali Bleeding Edge
Table of Contents
kali-bleeding-edge is the name of a Kali
repository that you can enable in your
APT configuration to have access to packages built with the latest
version of the source code found in the upstream git repository.
Ensure you have the latest version of a specific tool
With over 300 tools in our repository, it’s close to impossible for us to keep every tool updated to their latest git version all the time - it’s already hard to do with official releases. However there are certainly cases where you really want the latest version. Consider this:
You have an audit tomorrow, and you’re getting your tools ready. You boot
Kali Linux up, run
sudo apt update && sudo apt full-upgrade to make sure
that you are running the latest stable versions of $your_favorite_tool. After
the update, you notice that it was updated to last week’s version.
However, in the past week, some pretty awesome updates were added to
the git repository of $your_favorite_tool, and you really need those new
features for the upcoming assessment. What do you do?
git clone the upstream repository in your home directory and
work from there but then you lose any integration with Kali. You also
have to take care of dependencies manually. No, the smartest solution
is to rely on the tireless work of our Kali Bot that constantly crunches
upstream git repository to populate our kali-bleeding-edge repository.
Verify bug fixes committed by upstream authors
You’re an avid user of $your_favorite_tool and you have found some bug. As a good open source citizen, you checked the upstream project on GitHub, saw that the bug was not yet reported and you sent a detailed report on how to reproduce the issue.
Thanks to this, the upstream developer identified the problem, committed a possible fix and asked you to verify whether the problem is fixed with the latest git version.
You like the tool and the open-source philosophy, but you’re not a developer and don’t really want to build a git version of the tool just for this.
Thankfully, you remember the kali-bleeding-edge repository and after a quick check on pkg.kali.org you notice that the Kali bot already prepared an updated package. You quickly install it and reply to the upstream developer with the desired confirmation (or further information).
Caution: watch for the blood
Remember that it’s called “Kali bleeding edge” for a reason. While the poor Kali bot does its best, its AI is not always smart enough to detect new dependencies, backward incompatible changes, and any other instructions left by the upstream developer in the README. So while it will usually manage to build some package, there’s no guaranty that the updated package will work.
Some upstream developers deliberately break their tool while they are working on some refactoring, or other major changes. They recommend their users to use only the official releases. In that case, the kali-bleeding-edge package will be useless if not actively harmful (the non-finished code could for example break some of the data managed by the tool).
Thus it’s a good idea to have a look at the changes that landed in the upstream git repository before deciding to upgrade a package to its kali-bleeding-edge version.
How to enable the repository
Ok. You have been warned and you promised to use kali-bleeding-edge in a reasonable way. How do you enable that repository? Easy:
[email protected]:~$ sudo tee /etc/apt/sources.list.d/kali-bleeding-edge.list <<EOF deb http://http.kali.org/kali kali-bleeding-edge main contrib non-free non-free-firmware EOF [email protected]:~$ sudo apt update [...]
If you later want to disable the repository, it’s as easy as removing the file that you just created:
[email protected]:~$ sudo rm -f /etc/apt/sources.list.d/kali-bleeding-edge.list
Install a package from kali-bleeding-edge
Once the repository has been enabled, installing a package from
kali-bleeding-edge is trivial with
apt install <package>/kali-bleeding-edge. Here’s an example for gitleaks:

Notice that the versioning scheme is a bit special. It starts with the
version of the last upstream release and is followed by
<date> is the date of the last
<number> is a simple increment to cater for multiple
versions in the same day, and
<commit> is a short commit identifier).
The Debian revision contains
~jan+nus<X> indicating that this is
a “new uptsream snapshot” (
nus) that was created by the Janitor
Bot (which powers the
Kali Bot). The tilde ensures that this
sorts lower than any subsequent manual release of the same version.
Be aware that once you have installed a package from kali-bleeding-edge,
apt will continue to fetch updates for that package from this repository
for as long as the kali-bleeding-edge version is newer than the
Switch back to the stable version
If you want to go back to the stable version of the package, it works the same way, except that you set the target distribution to kali-rolling:
