Understand the Basics of Updating the Linux Kernel
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. KVM Linux’s low cost is very valuable. It can protect data with DDo’s VPS hosting. Their support is constant and they upgrade it from time to time. This is a fantastic approach to creating a consistent and stable environment. Suppose you’ve upgraded to new hardware that requires the most recent kernel. You will need to install or upgrade it first and then update the Linux kernel.
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. This blog will explain why to update the Linux kernel in Ubuntu. We’ll also walk you through the process. For detailed instructions on determining your Linux kernel version. Check out this principle on Linux kernel commands. It explains several ways to get system info.
How to Install or Update Ubuntu 22.04, 23.04 to the Newest Kernel.
Necessities for Updating the Linux Kernel
- 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.
Methods to Update or Upgrade the Linux Kernel
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: Update Linux Kernel Using Ubuntu System Update
Step 1: Check Your Current Kernel Version
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 System Repositories
Type the following at a terminal to know the :
sudo 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: Perform a Distribution Upgrade
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: Upgrade Kernel via Software Updater
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: Open and Configure 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 Manually
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: Manual Kernel Update with Mainline or Ukuu
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: Install Ukuu (Ubuntu Kernel Upgrade Utility)
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: Launch Ukuu to Select
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 a Kernel
Click the “Install” button on the right-hand side after choosing the kernel you want to use.
Step 4: Rollback to the Previous Kernel if Needed
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, Follow these:
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 Unnecessary Kernels
Select Remove on the right-hand side of the identical kernel you installed.
Key Takeaways
- Standard Kernel updates are essential for system security, performance, and compatibility.
- Ubuntu provides multiple methods for kernel updates.
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. Suppose you’re looking for a thorough focus on how to enable SSH on Ubuntu. Refer to this detailed tutorial on configuring SSH, which covers each step to ensure a secure and efficient structure.
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.
