To switch kernel versions in Ubuntu, you can follow these steps:<\/p>\n

    \n
  1. Open the terminal and use the following command to list the installed kernel versions in the system:<\/li>\n<\/ol>\n
    dpkg --list | grep linux-image\r\n<\/code><\/pre>\n
      \n
    1. Download the needed kernel version from the official Ubuntu source, for example, if you want to install Linux kernel version 5.4.0-42.<\/li>\n<\/ol>\n
      sudo apt-get install linux-image-5.4.0-42-generic linux-headers-5.4.0-42-generic\r\n<\/code><\/pre>\n
        \n
      1. After the installation is complete, you need to restart the system and select the newly installed kernel version at startup.<\/li>\n
      2. To remove old kernel versions, you can use the following command:<\/li>\n<\/ol>\n
        sudo apt-get purge linux-image-x.x.x-x-generic linux-headers-x.x.x-x-generic\r\n<\/code><\/pre>\n
        “x.x.x-x” is the old kernel version number to be deleted.<\/p>\n
        Please note that switching kernel versions may lead to system stability and compatibility issues, so it is recommended to back up important data before switching.<\/p>\n","protected":false},"excerpt":{"rendered":"
