Easily upgrade Linux Kernel in Ubuntu and Linux Mint
You can upgrade Linux kernel on your own in Linux command line with a few apt-get commands
. But the kernel upgrade procedure is much easier and more convenient with a GUI tool called Ukuu (Ubuntu Kernel Update Utility).
This GUI tool is developed by Tony George who has provided us with several other useful tools for Ubuntu such as battery monitor for Ubuntu, app backup tool Aptik etc.
Warning: Before we see how to upgrade Linux kernel in Ubuntu with Ukuu, I must warn you that you should be aware of the risk. If something goes wrong, you may revert to a previous Kernel version but you must not panic. Make a backup of Ubuntu system to be sure. If you are easily baffled with troubleshooting, avoid playing with manual upgrades and stick to your distribution’s system updates.
Step 1: Install Ukuu in Ubuntu and Linux Mint
There is an official PPA provided by the developer to install this tool. Just use the commands below to install Ukuu:
sudo add-apt-repository ppa:teejee2008/ppa
sudo apt-get update
sudo apt-get install ukuu
Step 2: Using Ukuu to install latest Linux Kernel in Ubuntu
Once you have installed Ukuu, start it. It will refresh the list of available Linux kernels available for Ubuntu. By default, it will show you all the available kernels, including the unstable release kernel (tagged with RC and with red Tux icon). Kernel versions from the distributions are labeled with the logo and the other versions have just the good old Tux logo.
Needless to say that you should avoid the release candidates. Select the desired Kernel version and click on install to install the newer Linux kernel version.
Of course, it will require admin password for this action. Once you have entered your password, you can see the installation progress in the application itself. Focus on the end result to know if it new Linux kernel was installed successfully or not.
Note: If the installation fails, no need to panic. Nothing will be wrong the system. Just try a different Kernel version and it might work.
Once installation finishes, you’ll see a very helpful screen that tells you if anything goes wrong with the new Linux kernel, you can always choose to boot into the older kernel from the grub menu.
When you boot into the system next, you’ll be running the Linux kernel you had just installed.
One thing to note here is that installing a new kernel doesn’t mean that the older kernel has been removed from the system. It remains at your disposal. By default, Ubuntu boots into the newest Linux Kernel installed on the system.
