Tip: Installing specific Linux kernel version

In the case that you ever needed to install a specific Linux kernel version in order to run a particular release, here are some quick tips.
Note: This will only apply to Ubuntu/Debian users as RHEL/CentOS users won’t ever have such a need.

  1. (Optional) Check that the particular image you are interested in is available to you.
    In a shell prompt, run: sudo apt-cache search linux-image | grep <version>-generic
    E.g., sudo apt-cache search linux-image | grep 3.19.0-80-generic

  2. Install the kernel image you need. You only need the kernel image.
    sudo apt-get install linux-image-<version>-generic
    E.g., sudo apt-get install linux-image-3.19.0-80-generic

    However, you can choose to install the extras too in order to be complete.
    sudo apt-get install linux-image-<version>-generic linux-image-extra-<version>-generic linux-headers-<version> linux-headers-<version>-generic
    E.g., sudo apt-get install linux-image-3.19.0-80-generic linux-image-extra-3.19.0-80-generic linux-headers-3.19.0-80 linux-headers-3.19.0-80-generic

  3. Reboot into the new kernel (make sure to select it in the GRUB menu on boot – See: https://askubuntu.com/questions/621393/how-to-change-kernel-at-boot)
