In this article, we will learn about some of the possible causes that a kernel installation using dpkg can cause, and then I will list some possible fixes that you can try to fix this problem. Installing with dpkg Using apt is so convenient that the nonessential tools are easy to forget, but the easiest way to install a compiled kernel is to use a command such as dpkg -i package. deb, where package.deb is the name generated by the Linux image package, for example linux-image-4.19.37-falcot_1_amd64.deb.

 

 

The Debian Kernel Package installs the kernel ( vmlinuz-version ), its configuration ( config-version ) and symbolizes its workstation ( System.map-version .). ) in / boot / . Finally, modules are installed in the / lib / modules / version / directory.

The package configuration scripts always create an initrd image, which is clearly a mini-system designed to be booted by a boot loader that takes up memory (hence the name, which simply means “init ramdisk”) of the boot loader. The kernel is loaded and used by Linux solely to load modules needed to access disks that contain a complete Debian system (for example, drivers for SATA hard drives). Finally, the most important post-installation scripts update the symbolic / vmlinuz , inlinks /vmlinuz.old , /initrd.img and /initrd.img.old to have users access the last two kernels and transfer initrd images

Most of these tasks are outsourced, so you can finally mount scripts in the /etc/kernel/*.d/ directories. Instance for integration with grub based on /etc/kernel/postinst.d/zz-update-grub and /etc/kernel/postrm.d / Call zz -update-grub to update-grub as soon as kernels are installed or removed.

8.11.1. Debian Kernel Package Functions

Using apt is so convenient that it’s easy to overlook minor implementations, but the easiest way to install any compiled kernel is to use a directive such as dpkg -i package. use .deb where package.deb is the package name of the Linux image, for example linux-image-4.19.37- falcot_1_amd64. deb .

The configuration steps described in this chapter are fundamental and can lead to the system or its workstation, as well as to massive semiautomatic continuation. However, this may not be enough to fully deploy the customized system. Some hAspects do not work and require configuration, including low-level programs known as Unix services.

In this mini-workshop, we will learn how to install the latest kernel on multiple Linux distributions.

What Is The Core

First, we define how the kernel a is defined. The Linux kernel is essentially the brain of your devices. Its main purpose is to facilitate communication between your hardware and your software. As a current example, when an application needs to make changes (such as changing your monitor’s screen resolution), the software sends a trust request to the kernel, and the kernel uses the available video driver options to force you to change the resolution.

Five types of kernels are available. They are marked as follows:

Now that we have a basic understanding of what a kernel is and what it wants to do, let’s install and / or update the upstream kernel to the latest version. We will take care of the basic kernel installation on the following operating systems:

Installing The Kernel

First, we will definitely considerm installing a kernel for CentOS and a new version of CentOS 8. Let’s start with CentOS from 7.
(Perhaps today we will only be able to access 64-bit updates.)

CentOS 7

First of all, we need to make sure that all of our kits are updated on the fly. To do this, we all run the yum update command.

Then some of us want to confirm that we are installing CentOS 7. Our command output will probably look like this.

Then we’ll take a look at our current kernel version. When we run the uname command, a similar usage is returned. (The number of kernel versions on your system may differ from some of the ones shown below)

If we analyze this output, it means that the information is tracked using the kernel version.

Now that we know our own kernel version, we can compare them – the latest available kernel versions. Then we can also add a new repository to match the latest kernel. We will be using a repository (or the elrepo Enterprise Linux package) that supports multiple RedHat / CentOS based work systems. We can accomplish this task inby running the following command.

This command will only give you output if the repository has not yet been added to your system. Then we run the command in your installation repository.

After that we check that the repository is installed correctly, and make sure that ELRepo is included in our set of available repositories.

We can see which of our lists ELRepo usually belongs to. The only thing we need to do is install the pending kernel version. We can deploy a new kernel by running the command.

The use of “ml” means “stable baseline” and indicates that the kernel was installed from the patch branch of the kernel archive. You can certainly double check your kernel version and see which one has the most recent performance available. Now, if we run the uname command expression, our result looks like this.

CentOS 8

We need to follow the same steps that we used for CentOS 7 above until we interact with the repository setup step.
