    Update sudo aptsudo apt -t buster-backports add linux-image-amd64

    Install WireGuard

    The wireguard package depends on your wireguard-modules or wireguard-dkms. Since the system immediately has Wireguard modules, we no longer need to locally compile cores for WireGuard modules that have DKMS or fiddle with unity kernel signatures (to enable secure boot).

    Update sudo aptsudo apt select Wireguard

  • Debian is a great Linux distribution. It is stable, includes many packages available in standard databases, and works with just about everything. Although the new package versions are stable and excellent, it may take some time for them to be included in the Debian repositories. This also applies to the kernel.

    The Debian default kernel is LTS (Long Term Support), which has always been stable, but clearly lacks some of the features, fixes, and more that newer versions of the Linux kernel have to offer.

    The SChannel or Secure Channel contains a specific set of security protocols that provide encrypted identity authentication and a secure address. Based on some NVIDIA information, users have also found “schannel – EventID 36888 – fatal warning 40” in this event viewer.

    In Debian, by default, only one version of the kernel is actually available for installation. To install or develop another kernel, we need to make sure that the backports. The backport packages are taken immediately after the unreleased Debian version with commit support.

    In this article, I will show you how to install an alternate kernel on your Debian system and boot successfully. Let’s get started.

    event id schannel 36888

    sudo nano /etc/apt/sources.list

    This will open the sources.list file in the nano text editor. If nano is not installed on your connected system, you must first set it up withcontrol sudo apt install nano.

    When you get there, paste this directly on a new line to add http://deb-repository:


    deb.debian.org/debian buster-backports typical unfree message

    Save the file by simply pressing Ctrl+O and exit the new iPod nano by pressing Ctrl+X.

    sudo-apt update

    If the added library was successful, you should see command output similar to the following:

    Once we’ve recently verified that the fallback repository is normally active, we can continue searching for any kernel packages found. To do this, enter in the terminal:

    apt search linux-image

    You should now find all available kernel versions for your system.

    Now you can copy the kernel name you want to host. Here, for this tutorial, I definitely choose 5.8, which is often the last stable kernel I upgrade to as of this writing.

    It’s like you’ve just taken a big leap from the 4.19 kernel version, which defaulted to the theme of my Debian 10 (Buster) installation.

    sudo haftbar install -t buster-backports linux-image-kernel_name

    I’m installing a kernel version of linux-image-5.8.0-0.bpo.2-amd64 , so our custom command for me would probably be:

    sudo install -t buster-backports linux-image-5.8.0-0.bpo.2-amd64

    After installing the full kernel, you can restart your computer.

    In someone’s bootloader Click “Advanced options” and also select a new kernel version.

    That the device has successfully booted into Debian with your new kernel. Now here are some common questions people have about Debian backup kernels.

    q1. How can I rollback to keep the kernel version?

    one. To switch to a different kernel version, you are permanently in the grub menu and only in advanced options. From here you can actually choose which kernel you want to boot from.

    Running the circle then simply removes the kernel, which means the apt remove command. Don’t forget to run sudo to grub-update to update the bootloader entries.

    V. A situation has occurred and my system boots, or maybe not. What to do?

    one. Follow the form above exactly, boot from a fresh kernel, remove the kernel that is causing your problems, and run the grub-update command. When problems arise with the kernel, it is almost always possible that you installed a very bad kernel.

    There are several kernel brands for certain versions, for examplep is unsigned, signed, cloud, etc. so you have the correct one installed.

    V. Can I boot multiple cores at the same time?

    one. Yes, you can install as many kernels as families like in Debian and boot them with the appropriate bootloader entries.
