Understanding First what Exactly It is

You should be aware, as a Ubuntu 22.04 user, that the present Linux kernel prioritizes stability. As over the most recent Linux kernel upgrades. This is a fantastic approach to creating a consistent and stable environment. If you’ve upgraded to new hardware that requires the most recent kernel. You will need to install or upgrade it first and then Linux kernel update.

The operating system’s brain, the Linux kernel, is in charge of controlling hardware. Also offering necessary services, and facilitating seamless user experiences. The Linux kernel on your Ubuntu system benefits from routine updates. In a variety of ways, from better performance to stronger security. We’ll explain the importance of updating the Linux kernel in Ubuntu in this blog article and walk you through the procedure. For detailed instructions on determining your Linux kernel version, check out this guide on Linux kernel commands, which explains several methods to obtain this important system information.

How to Install or Update Ubuntu 22.04, 23.04 to the Newest Kernel.

Requirements:

  • Ubuntu Linux Operating on a Server
  • Requires a User Account with sudo Privileges
  • The Ubuntu-built apt tool
  • The Ubuntu Update Manager is an Integrated Program.

Follow the guidelines provided to install or upgrade to the most recent Ubuntu kernel on Ubuntu 22.04, and 23.04. There are several options and will see in detail the options by which one can update the Ubuntu 22.04 kernel version.

Option 1: Updating Ubuntu Kernel via System Update Process.

Step 1: Verify the Version of the Current Kernel

In a terminal window.

uname –sr

The terminal output looks somewhat like this:

Linux 4.4.0-64 generic

The Ubuntu kernel package as a whole is indicated by the first two digits (in this case, 4.4). The version is represented by the third digit, while the degree of patches and fixes is represented by the fourth digit.

See our comprehensive guide on determining the Linux kernel version for more information. You can determine the version of Ubuntu you are using while examining the system.

Step 2: Update the Repositories

Type the following at a terminal to know the :

sudo apt-get update

command ubuntu apt get update

This command updates your local list of software, noting any fresher updates and revisions. The command will locate and mark a newer Ubuntu 22.04, 23.04 kernel version for download and installation if one exists.

Step 3: Run the Upgrade Command

In the terminal, continue to type:

sudo apt-get dist-upgrade

Ubuntu is instructed to handle all dependencies intelligently by the “dist-upgrade” switch. This command ensures that the second program is upgraded before the first if the functionality of one software package depends on another software package.

This method can upgrade the Ubuntu Linux kernel safely using this method. You can obtain the kernel updates that you can obtain with this tool have been examined and found.

Option 2: Push a Kernel Upgrade via the System Update Process

Some newer kernels may have been released, but you might not have extensively tested with your version of Ubuntu. As an illustration, suppose you are using Ubuntu 17.10 (Artful Aardvark) but are aware that Ubuntu 18.04 (Bionic Beaver) is also a possibility.

This method of updating the Ubuntu Linux kernel necessitates a more involved procedure.

Step 1: Back up any Crucial Files.

This is something you’ve already done, but it’s significant enough to mention again.

Step 2: Use the Software Updater.

By pressing the super key, which is typically the “windows” key on keyboards, you can start the software updater and look for Update Manager.

If necessary, the update manager will let you know. It ought to say that your PC is up to date if you follow the instructions in Part A. Select Settings from the menu. Several tabs should appear in a new window that opens.

Step 3: Configure the Software Updater.

On the Updates tab, click.

In the “Install updates from:” section, choose the first three checkboxes.

  • Improvements to the security system
  • Recommended Revisions
  • Updates not Supported

Then, find the drop-down menu that says “Notify me of a new Ubuntu version:” at the bottom of this tab.

Select By clicking that drop-down menu.

  • For versions with ongoing support (if you wish to continue with tried-and-true versions that come with complete support)
  • For any new version (If you enjoy using the most recent version and don’t mind if certain features are buggy)

Reopen this window once it has been closed. If a new version is available, it ought to give the user the choice to upgrade. (The upgrade often becomes accessible a few days after release, and the server traffic gradually decreases.)

Step 4: Force the Upgrade

If the system does not automatically offer an upgrade for some reason, you can force it by opening a terminal and typing:

update-manager –d

A window displaying the release notes for the new kernel (and version) of Ubuntu should appear in response from the system. If everything appears to be in order, click Upgrade to start the procedure.

Option 3: Leading Action for Updating the Kernel Manually

There is a third method for choosing and installing a new Ubuntu kernel if all you want to do is upgrade to the most recent (untested) kernel that is available and you’re aware of the dangers.

It’s important to check your system configuration before completing this step. Also, are you using any modified drivers, particularly video drivers? Any special packages or configurations? These might not work with the updated kernel. There should be a recovery mechanism provided. In case you make a mistake and discover the new kernel is incompatible. Yet, avoiding a problem altogether is preferable to trying to solve one.

Additionally, going by reading notes for the Ubuntu Linux kernel you wish to install is a smart idea. Make a note of the revision number and any features you plan to use. Ukuu, a graphical tool for updating the kernel, was used during this operation. Other approaches include getting a copy of the source code and building it. Also manually downloading and installing the kernel, or even both. These techniques are more difficult and not covered in this manual.

Step 1: First of all, Set up Ukuu

Type the following in the terminal and press Enter after each line:

sudo apt-add-repository ppa:teejee2008/ppa

sudo apt-get update

sudo apt-get install ukuu

Step 2: After Setting up in the First Step, Start Ukuu

Type the following on the keyboard:

sudo ukuu-gtk

The Ukuu program will start up and should show a list of the Linux kernel versions that are currently available.

Step 3: Install the Kernel

Click the “Install” button on the right-hand side after choosing the kernel you want to use.

Step 4: Restart the Computer, Once you Install

Restart your system after the Ubuntu kernel has been installed. You can reopen Ukuu to check the installation once you’re back in the OS.

Step 5: If Step 4 Doesn’t Work

The GRUB boot utility will preserve a copy of the previous kernel that you can choose to boot onto in the event of a catastrophic issue.

Select Ubuntu’s Advanced settings, then choose the prior kernel (detailed by the revision number), from the boot screen. There is no requirement to use the “recovery mode” or “upstart”

Step 6: Remove the Kernel

Simply select Remove on the right-hand side of the identical kernel that you previously installed.

Final Thought on Updating Linux Kernel In Ubuntu

Update system packages before updating the most recent Linux kernel on Ubuntu 22.04. then verify the kernel version as it stands. Then launch the Ubuntu Mainline Kernel Installer application. Using “$ sudo apt install mainline -y” in the terminal of Ubuntu 22.04, 23.04. If you’re looking for a thorough guide on how to enable SSH on Ubuntu, refer to this detailed tutorial on configuring SSH that covers each step to ensure a secure and efficient setup.

The next step is to launch the installed program. Choose the most recent Ubuntu kernel version, and then click the install button. Restart the system to finish. This blog describes how to upgrade or install the most recent Linux kernel on Ubuntu 22.04,23.04. Ubuntu must update the Ubuntu Linux kernel to improve security. Ensure that hardware compatibility, and maximize system performance.
