    The Linux kernel is similar to the central kernel of an operating system. It acts as a kind of intermediary and provides an interface between software applications and simple computer hardware.

    The Linux kernel is the special foundation on which all the different types of Linux work. It is open source software – anyone can decompile, study, and modify the code.

    With further development, developers discover patch updates as well as the Linux kernel. These airbags can improve safety, add functionality, or simply increase the speed at which the operating system actually runs.

    If you are using a Linux operating system (such as Ubuntu), it is recommended that you regularly updateand update the kernel.

    • Web server running Ubuntu Linux
    • Terminal access (CTRL-ALT-T or Application menu> Accessories> Terminal)
    • User account now with sudo permission
    • Ubuntu’s built-in apt tool
    • Ubuntu’s built-in update manager (optional)

    Ubuntu Kernel Upgrade Guide

    Option A. Use These System Update Processes

    Step 1. Check your current kernel version

      uname - sr  
      Linux 4.4.0-64 Generic  

    First, two (in paragraphs of indictment 4.4) are the entire kernel package. The third number is the version, and the fourth number also indicates my patch and patch level.

    For more information, see the Complete Linux Kernel Package Inspection Guide. During a system check, you will also be able to check which version of Ubuntu you are using.

    Step 2. Update our own repos

      sudo apt-get update  

    This command updates your final local SEO software and takes into account the latest changes and even updates. If there is a newer one for the kerneloption, it will find the command and mark it for download and install.

    Step 3. Update type

      sudo apt-get dist-upgrade  

    The “dist-upgrade” switch allows Ubuntu to gracefully handle all dependencies. However, if the specific requirement depends on the launch package of another software toolkit, this command ensures that the second is most likely to be updated before the first is updated.

    This is a safe strategy for upgrading the Ubuntu Linux kernel. Kernel updates available through this utility have been tested and confirmed to work with a version that points to Ubuntu.

    Option B: Use The System Update Process To Force A Kernel Update

    What is the latest Linux kernel version available for download?

    At the time of this article’s update, Linux 5.14 is the most advanced version available for download. There are actually several ways to update Linux kernel on Ubuntu 20.04 LTS operating platform. You can also take this opportunity to install or update the Linux kernel on the Linux Mint operating system.

    There are times when another kernel has been released but has not been thoroughly tested, your version belongs to all Ubuntu. For example, you could use Ubuntu 17.10 (Artful Aardvark) a little more and also know that ubuntu .04 18 (Bionic Beaver) is available.

    ubuntu upgrade linux kernel

    Updating the kernel in this way requires a significant additional process.

    Step 1. Back up your important files

    You’ve probably done this beforeshe, but it is important enough that the repetition be repeated so seriously.

    Step 2. Software Updater

    Run the software update program by pressing the superkey (Windows key on most keyboards) and searching for Update Manager.

    Update Manager will notify you when updates are needed. After completing the steps in Part A, you should have the latest version installed on your desktop computer.

    Step 3. Configure the Software Updater

    • Important security updates
    • Updates are recommended
    • Updates are not supported

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

    • For long-term support versions (when a person wants to stick with fully supported versions, tested or reliable versions)
    • For a new type of version (if you want to learn how to play with the latest and greatest, and do not think about it when something is wrong)

    Close this window and open this item again. It should offer an upgrade option when a new version is available. (Usually, updates become available and the traffic server gets brighter a few days after they are released.)

    Step 1. Force update

    If for some reason the system doesn’t perform a good update, you can force it to run by opening a terminal and typing:

      Update Manager - d  

    In response to the procedure, a window should appear with the release notes for the latest version (and kernel version) of Ubuntu.

    If all the details are in order, click “Refresh” and you will see the process continue.

    Option C: Manually Update The Kernel (advanced Procedure)

    If you just want to upgrade to an affordable modern (untested) kernel and are aware of the risks, there is a 1/3 step-by-step guide to choosing and installing a completely new kernel.

    It is useful to check your system configuration before performing this step. Do you use custom services (especially video pilots from a delivery service)? Custom configwalkie-talkies, maybe packages? They may not work with the new kernel.

    If you make a mistake and find that the new mainline is incompatible, the dependency recovery option should be available. But it is better to take action and prevent the problem than to try to find a solution.

    This is also a good way to find out what release notes are available for the kernel you plan to install. Make a note of the version number and features you want to handle.

    This process uses the important graphical utility Ukuu to ensure there is no doubt about updating the kernel. There are other methods, including downloading and installing the file manually, and this could be the kernel, usually even getting a copy of the source code and compiling it. These methods are more complex and beyond the scope of this tutorial.

    Step 6. Install Ukuu

    Enter all of the following data into the terminal (press Enter after the swift line):

      sudo apt-add-repository ppa: teejee2008 / ppa  
      sudo apt-get update  
      sudo apt-get ukuu  

    The put in first command adds open source TeeJeeTech software Take the code for the Linux repositories to your base repositories. The fourth command updates the database so that you have a list of current revisions. The third team installs the Ukuu software.

    Step 2. Launch Ukuu

      sudo ukuu-gtk  

    The Ukuu utility is encouraged and run to display a list of submitted Linux kernel versions.

    Step 3. Install the exact kernel

    Select the kernel you want to install, then click the Install link on the right.

    Step 4. Reboot the system

    After completing your kernel investment, reboot your system. When you return to the operating system, you can restart Ukuu Verification for installation.

    In the event of a serious, catastrophic GRUB problem, the Boot Alias ​​utility keeps a copy of the old kernel from which you can choose to boot.

    ubuntu upgrade linux kernel

    Boot into the projection screen, select Advanced Options for Ubuntu, and then select the previous kernel (identified with the resolution by version number). It is not at all necessary to use the “climber” option, perhapsoption “recovery mode”.

    Step 6. Remove the kernel

    The Ukuu utility also offers an inexpensive way to remove old kernels via Ubuntu. Just click on the same kernel you installed earlier and click the Uninstall button on the right.

    Upgrading the Ubuntu kernel is fairly straightforward for the maximum number of users. Most systems will likely require an upgrade, which they will most likely do. However, if you’re looking for a workable custom kernel or want to bypass an automated process, this guide is a good place to go.
