Want to install the latest Linux Kernel? A simple script can always do the job and make things easier in Ubuntu.

Michael Murphy has created a script makes installing the latest RC, stable, or lowlatency Kernel easier in Ubuntu. The script asks some questions and automatically downloads and installs the latest Kernel packages from [Ubuntu kernel mainline page][1].

### Install / Upgrade Linux Kernel via the Script: ###

1. Download the script from the right sidebar of the [github page][2] (click the “Download Zip” button).

2. Decompress the Zip archive by right-clicking on it in your user Downloads folder and select “Extract Here”.

3. Navigate to the result folder in terminal by right-clicking on that folder and select “Open in Terminal”:

It opens a terminal window and automatically navigates into the result folder. If you **DON’T** find the “Open in Terminal” option, search for and install `nautilus-open-terminal` in Ubuntu Software Center and then log out and back in (or run `nautilus -q` command in terminal instead to apply changes).

4. When you’re in terminal, give the script executable permission for once.

    chmod +x *

FINALLY run the script every time you want to install / upgrade Linux Kernel in Ubuntu:

    ./*

I use * instead of the SCRIPT NAME in both commands since it’s the only file in that folder.

If the script runs successfully, restart your computer when done.

### Revert back and Uninstall the new Kernel: ###

To revert back and remove the new kernel for any reason, restart your computer and select boot with the old kernel entry under **Advanced Options** menu when you’re at Grub boot-loader.

When it boots up, see below section.

### How to Remove the old (or new) Kernels: ###

1. Install Synaptic Package Manager from Ubuntu Software Center.

2. Launch Synaptic Package Manager and do:

- click the **Reload** button in case you want to remove the new kernel.
- select **Status -> Installed** on the left pane to make search list clear.
- search **linux-image**- using Quick filter box.
- select a kernel image “linux-image-x.xx.xx-generic” and mark for (complete) removal
- finally apply changes

Repeat until you removed all unwanted kernels. DON’T carelessly remove the current running kernel, check it out via `uname -r` (see below pic.) command.

For Ubuntu Server, you may run below commands one by one:

    uname -r
    
    dpkg -l | grep linux-image-
    
    sudo apt-get autoremove KERNEL_IMAGE_NAME
