In this guide, we have given 7 different ways to update Linux kernel for Ubuntu. Among the 7 methods, five methods requires system reboot to apply the new Kernel and two methods don\u2019t. Before updating Linux Kernel, it is\u00a0highly recommended to backup your important data!\u00a0<\/strong>All methods mentioned here are tested on Ubuntu OS only. We are not sure if they will work on other Ubuntu flavors (Eg. Xubuntu) and Ubuntu derivatives (Eg. Linux Mint).<\/p>\n

Part A \u2013 Kernel Updates with reboot<\/h2>\n

The following methods requires you to reboot your system to apply the new Linux Kernel. All of the following methods are recommended for personal or testing systems. Again, please backup your important data, configuration files and any other important stuff from your Ubuntu system.<\/p>\n

Method 1 \u2013 Update the Linux Kernel with dpkg (The manual way)<\/h4>\n

This method helps you to manually download and install the latest available Linux kernel from\u00a0kernel.ubuntu.com<\/a><\/strong>\u00a0website. If you want to install most recent version (either stable or release candidate), this method will help. Download the Linux kernel version from the above link. As of writing this guide, the latest available version was\u00a05.0-rc1<\/strong>\u00a0and latest stable version was\u00a0v4.20<\/strong>.<\/p>\n

\"\"<\/a><\/p>\n

Click on the Linux Kernel version link of your choice and find the section for your architecture (\u2018Build for XXX\u2019). In that section, download the two files with these patterns (where X.Y.Z is the highest version):<\/p>\n

    \n
  1. linux-image-*X.Y.Z*-generic-*.deb<\/li>\n
  2. linux-modules-X.Y.Z*-generic-*.deb<\/li>\n<\/ol>\n

    In a terminal, change directory to where the files are and run this command to manually install the kernel:<\/p>\n

    $ sudo dpkg --install *.deb<\/pre>\n
    Reboot to use the new kernel:<\/p>\n
    $ sudo reboot<\/pre>\n
    Check the kernel is as expected:<\/p>\n
    $ uname -r<\/pre>\n
