+**METHOD 1:**
 The easiest way to install a newer kernel in Debian, is to install it from the backports.
 In order to install a kernel from the backports, we need to add the backports-repository for your Debian version to the apt-sources and update the list of available packages:
@@ Line 4: / Line 6: @@
 **Add following line to /etc/apt/sources.list:**
-<code>deb http://deb.debian.org/debian buster-backports main<\code>\\
+<code>
-<code>sudo apt-get update <\code>\\
+deb http://deb.debian.org/debian bullseye-backports main
+</code>
+<code>
+sudo apt-get update
+</code>
+Now you can search for kernels:
+<code>
+sudo apt search linux-image
+</code>
+At this point, you can either install a specific version manually or choose to go for the latest release. To install the latest release, including necessary dependencies:
+<code>
+sudo apt -t bullseye-backports upgrade
+</code>
+After the upgrade, you can simply perform a reboot and the new kernel should be activated as the new default.
+<code>
+uname -r
+</code>
+**METHOD 2:**
+<code>
+sudo apt update && sudo apt upgrade -y
+</code>
+Add following to sources.list:
+<code>
+echo "deb http://deb.debian.org/debian unstable main contrib non-free" | sudo tee -a /etc/apt/sources.list
+</code>
+<code>
+echo "deb-src http://deb.debian.org/debian unstable main contrib non-free" | sudo tee -a /etc/apt/sources.list
+</code>
+Next, an easy solution is to use apt-pinning to avoid having different version branches causing your system prompting for updates from the experimental repository. Open the following file using a text editor.
+<code>
+sudo nano /etc/apt/preferences
+</code>
+Next, add the following.
+<code>
+Package: *
+Pin: release a=bullseye
+Pin-Priority: 500
+Package: linux-image-amd64
+Pin: release a=unstable
+Pin-Priority: 1000
+Package: *
+Pin: release a=unstable
+Pin-Priority: 100
+</code>
+Save it and get out (Ctrl-O and CTRL-X).
+The order goes all updates are preferenced to Bullseye with a higher score (500) than unstable (100), so you are not prompted on various packages to be updated from the unstable repository.
+However, to make it easy to keep the kernel up to date when you run the apt update command for your standard Bullseye packages, the example above has set linux-image-amd64 as a high priority (1000) using the unstable repository above any other source for that package only.
+Next:
+<code>
+sudo apt update
+</code>
+<code>
+sudo apt upgrade
+</code>
-<code>make</code>
-<code>sudo make install</code>
