Debian kernel update
Debian is widely recognized as a reliable and robust Linux distribution. Its stability and extensive package repositories make it a popular choice for both personal and enterprise use. However, one drawback of using Debian is the time it takes for new package versions to become available in the official repositories.
In order to keep up with the latest software releases and security updates, it is sometimes necessary to update the kernel manually. By updating the kernel, users can take advantage of new features, performance improvements, and bug fixes that may not be available in the default Debian repositories.
To update the kernel in Debian, users have several options. One option is to use the backports repository, which provides newer versions of packages that are not yet available in the stable release. By enabling the backports repository and using the package manager, users can easily update their kernel to a newer version.
Another option is to use a third-party repository, such as the Debian Kernel Team's repository. This repository provides the latest stable versions of the Linux kernel, allowing users to update their kernel without waiting for it to be included in the official Debian repositories.
Alternatively, users can choose to compile and install the kernel manually. This method requires more technical knowledge and can be time-consuming, but it offers the most flexibility and control over the kernel configuration.
Regardless of the method chosen, it is important to follow the appropriate documentation and guidelines provided by Debian or the respective repository. This ensures a smooth and successful kernel update without compromising the stability and integrity of the Debian system.
Step to Step guide how to make Debian kernel update
Updating the Debian kernel affects system files and may impact system stability. Superuser privileges are required to perform this action, which can be obtained using the sudo command (for example, before each command) or by using sudo su to switch to superuser mode.
You can find out the current kernel version using the following command:
# uname -a
The latest kernel version is available in the backports repository. You need to add it to the list of repositories in your system.
echo "deb http://ftp.debian.org/debian/ stretch-backports main non-free contrib" >> /etc/apt/sources.list apt-get update
To determine the code name of your Debian version, use the following command:
grep VERSION_CODENAME /etc/os-release
When adding the backports repository, replace the code name (the word stretch in the example above) with the code name corresponding to your Debian version (e.g., buster, bullseye, bookworm).
Example command for bookworm:
# echo "deb http://deb.debian.org/debian bookworm-backports main" | sudo tee /etc/apt/sources.list.d/backports.list
After this, you need to update the repository list:
# apt-get update
Searching for available kernel versions for installation
# apt search linux-headers v linux-headers - v linux-headers:i386 - v linux-headers-3.0 - v linux-headers-3.0:i386 - p linux-headers-4.15.0-1004-oem - Linux kernel headers for version 4.15.0 on 64 bit x86 SMP p linux-headers-4.15.0-1006-gcp - Linux kernel headers for version 4.15.0 on 64 bit x86 SMP p linux-headers-4.15.0-1006-oem - Linux kernel headers for version 4.15.0 on 64 bit x86 SMP p linux-headers-4.15.0-1007-aws - Linux kernel headers for version 4.15.0 on 64 bit x86 SMP p linux-headers-4.15.0-1007-oracle - Oracle Linux kernel headers for version 4.15.0 on 64 bit x86 SMP p linux-headers-4.15.0-1008-gcp - Linux kernel headers for version 4.15.0 on 64 bit x86 SMP p linux-headers-4.15.0-1008-kvm - Linux kernel headers for version 4.15.0 on 64 bit x86 SMP p linux-headers-4.15.0-1008-oem - Linux kernel headers for version 4.15.0 on 64 bit x86 SMP p linux-headers-4.15.0-1008-oracle - Oracle Linux kernel headers for version 4.15.0 on 64 bit x86 SMP ...
Select the required version from the list of available packages and install it
# apt install linux-headers-[version number]-bpo.1 linux-image-[version number]-bpo.1
The installation process will update Grub and will require a server restart to apply the changes.
Conclusion
You can use this post to update your Debian Kernel or to install it.
A kernel change can sometimes cause problems, resulting in a few programs not working. On the other hand, Debian has the advantage of allowing you to install multiple kernel versions on the same system. The bootloader menu allows you to switch to another kernel easily.
