Install KernelCare in Debian 11

Hello, friends. In this post, you will learn how to install KernelCare on Debian 11. In addition, we will tell you more about this security utility.

According to the tool’s website,

KernelCare Enterprise is a live kernel patching service that provides security patches and bugfixes for a range of popular Linux kernels that can be installed without rebooting the system.

Some of its key features are

  • Rebootless Linux Kernel Patching & Custom Patching
  • Works On-prem & in the cloud
  • Private patch server for gated infrastructures – ePortal
  • Out-of-the-box integration with patch management & vulnerability assessment tools

While it sounds pretty good, it is also geared towards professional environments as it is not completely free. However, in the trial time they offer you can get to love it.

So let’s go for it.

Installing KernelCare on Debian 11

Debian 11 is part of the systems that are supported by KernelCare, so we will have no problem installing it.

First, as I always recommend, update the system

sudo apt update
sudo apt upgrade

KernelCare has an installation script that makes everything easy. However, before you run it and install it, you should purchase a 7-day trial license.

Then, you can run

wget -qq -O - | bash
Install KernelCare on Debian 11
Install KernelCare on Debian 11

This way, the script will take care of everything necessary to install it properly.

From the official documentation, they tell us that “If you are using IP-based license, nothing else required to be done”.

But in case you have a Key

/usr/bin/kcarectl --register [key]

Obviously, replace [key] with the serial of your key.

And that’s it!


KernelCare is that kind of tool that can help improve the security of server-focused distributions. Besides that, it supports many distributions and is serious in its development.
