How can I upgrade the Ubuntu LTS kernel to newer?


New deployments of 12.04.2 will be installed with an updated kernel and a new X windows stack. For existing 12.04 deployments, users will need to opt-in to what is being called the LTS Hardware Enablement Stack. If you already have Ubuntu 12.04 installed with an earlier kernel stack, it is recommended that you keep this stack in place rather than switching to a later kernel; the newer kernel and X stacks are provided for enablement of hardware not supported by earlier kernels, and there is generally no reason to upgrade to a newer stack if your hardware is supported by the default kernel.

In order to upgrade to the 3.5 kernel on 12.04.2, you will need to run the following command(s):

For the new kernel:

sudo apt-get install linux-generic-lts-quantal

For the new X stack:

sudo apt-get install xserver-xorg-lts-quantal

WARNING: If you are using the xorg-edgers PPA, do not install the xserver-xorg-lts-quantal package as this will most likely result in...

I just installed Ubuntu 12.04.2 64-bit on my desktop PC and I see the kernel in System Monitor is 3.5.0-23 but in Ubuntu 12.04.2 in my laptop the kernel is 3.2.0-38.

I have already tried to run the command sudo apt-get upgrade && sudo apt-get dist-upgrade on my laptop but it doesn't update the kernel.

How can I upgrade kernel for my laptop?

Of course you can install 3.5.0 kernels, run apt-get install linux-image-generic-lts-quantal to install the latest quantal 3.5.0 kernel. This package will ensure that you always have the latest quantal kernel.

I personally recommend raring's 3.8 (base on upstream 3.8.8) kernel anyway.

NOTE: search for available 3.5.0 kernels apt-cache search linux-image-3.5.0.

BTW: You can even manually download latest mainline kernels and install them, for example 3.7.9. However, if you install PPA mainline kernels manually, you'll have...

Brief: This article shows you how to upgrade to latest Kernel easily with GUI tool Ukuu. Though the article is tested for Ubuntu, it should also work for other Ubuntu based Linux distributions such as Linux Mint, elementary OS, Linux Lite etc.

I am assuming that you already know what is Linux kernel. This is the core software that drives any Linux distribution. All the Linux distributions use the kernel at their core topped with Shell and then GUI elements. This is what Linus Torvalds created 25 years ago and this is what he still works on.

A newer version of Linux kernel is released every few months with new features (such as support for more hardware), bug fixes etc.

Should you upgrade to the latest Linux kernel, manually?

An average user doesn’t upgrade the Linux kernel on its own. He/she waits for the Linux distribution to provide the kernel upgrade. In fact, a significant number of desktop Linux user don’t care which Linux Kernel they are...

LTS Enablement Stacks

The Ubuntu LTS enablement (also called HWE or Hardware Enablement) stacks provide newer kernel and X support for existing Ubuntu LTS releases. These enablement stacks can be installed manually but are also available when installing with Ubuntu LTS point release media. These newer enablement stacks are meant for desktop and server and even recommended for cloud or virtual images. However, if one wants to remain on the original GA (General Availability) stacks, the options are:

Install from a previous 12.04.0/12.04.1/14.04.0/14.04.1/16.04.0/16.04.1 point release and update. Previous releases are archived at

Perform an update or upgrade to an LTS release from a previous release.

Perform a network install using the netboot images rather than the new -netboot images.

Now that the Ubuntu 17.10 release is officially out many of you will be faced with the decision of whether to upgrade, or not.

In this post we’ll show how to upgrade to Ubuntu 17.10 from Ubuntu 17.04, plus provide a few pointers to those of you who want to upgrade from 16.04 LTS.

As we mention in our full Ubuntu 17.10 run-down, the latest short-term release is packed full of big changes and major additions. There’s a new desktop, a new display server, a new display manager, a new kernel, a new …Well, I’m sure you get the idea!

In all it’s a pretty compelling upgrade, especially if you’re currently running Ubuntu 17.04.


Before attempting any Ubuntu upgrade there a couple of things you should always do.

First, make a backup of any/all important files and folders. While these shouldn’t get lost during the transition, there’s always an outside risk they might.

Secondly, make sure you have installed all updates to...

said in How can I upgrade kernel to new version?:

however, manjaro has a better GUI tool (manjaro-settings-manager) for updating the kernel.

We don’t support multiple kernel versions (meaning multiple versions of the same kernel variation—examples of variations core (default), LTS, Zen, CK, etc) Just like Arch, only the latest version of each variation is supported. So there is no need for a GUI to change kernels because there is only one version of each available. That is in contrast to Manjaro which makes several versions of the same kernel variation available. I personally dont see the benefit of that, but obviously some do...

about compiling a stable version of the Linux kernel on a Ubuntu/Debian Linux

. I wanted to install the same using apt-get command. How can I install the latest (mainline) Linux kernel on Ubuntu Linux?

Installing a brand new kernel on server or desktop is not recommended. The latest version might be buggy and can crash your system. However, if you need the latest version try the following instructions.

Method #1: Search and install the latest stable version

I tested this method on the following version of Ubuntu:

$ lsb_release -a No LSB modules are available. Distributor ID: Ubuntu Description: Ubuntu 16.04.2 LTS Release: 16.04 Codename: xenial

To find out your current version of Linux kernel, run:
$ uname -mrs
Linux 4.4.0-83-generic x86_64
To find out the latest version of Linux kernel type:
$ apt-cache search linux-generic
Sample outputs:

Ubuntu 16.04 is a Long-Term Support (LTS) release that will be supported by Canonical until April 2021. This guide explains how to upgrade your Linode from Ubuntu 14.04 (Trusty Tahr) to Ubuntu 16.04 (Xenial Xerus).

Distribution upgrades sometimes yield unpredictable results. If possible, use these steps as an alternative to the upgrade method described in this guide:

Create a new Linode with the latest disk template Rebuild your stack Transfer your data Swap IP addresses

The upgrade may be incomplete or your system may be corrupted if your internet connection is interrupted. Use Lish or Glish to perform this upgrade in a stable environment that does not rely on an active internet connection to your Linode.

Important: Ubuntu 16.04 ships with OpenSSH 7.2p2, which does not allow ssh-dss host authentication, or use of the SSH version 1 protocol.

I have various high-end PC’s, because I am really fond of lightning-fast hardware. But my development machines sometimes have issues with older kernels, because the drivers in the Ubuntu 12.04 LTS kernels that I run are outdated and do not support the kick-ass and brand-new hardware.

The reason I run 12.04 LTS is that most servers (I work with) run that version. And by running the latest long-term-stable on your development environment you can avoid writing software that cannot run on your production system, because it would simply not work there as well.

Even when you are limited to Ubuntu 12.04 LTS there are still many things you can choose. One thing you can tweak is your window manager. You can either run Ubuntu (using Unity), Xubuntu (with XFCE), Lubuntu (LXDE) or Kubuntu (KDE). You may run whatever variant you prefer, but Linus uses XFCE. My preference also goes to XFCE, and more particular Xubuntu, since it is lightweight and traditional in its...

Now that Ubuntu 18.04 LTS is officially released, you may want to upgrade your current Ubuntu installation to the Bionic Beaver. In this article, we will present you guides that will let you upgrade Ubuntu 16.04, 16.10, 17.04, and 17.10 to Ubuntu 18.04. The update is not yet pushed through the software update.

Typically, it takes around a week or two for the upgrade notification to propagate through entire repository sources. If you can wait until then, it seems like you are very patient and that’s a cool thing. But like me, if you can’t wait for so long, there is a way to force upgrade from the command line.

Upgrade to Ubuntu 18.04 LTS ‘Bionic Beaver’

Method 1: GUI Way

If you prefer GUI way of doing things, you can try upgrading to Ubuntu 18.04 from Software Update.

Step 1) Click “Activities”, and then launch “Software Update”.

Step 2) In the “Updates” tab, make sure you have selected either “For any new version” or “FOr long-term...

Ubuntu has two types of releases, standard and Long Term Support (or "LTS"). Standard updates are released every six months and receive security updates from Ubuntu for at least nine months, while LTS updates are released every two years and are supported for at least five years.

If you are currently using Ubuntu 12.04, you will have security updates until at least October 2017. If you want to extend that support time, and get access to new features and updates, you can upgrade your server to the newest LTS release. In this guide, we will go over how to safely upgrade an Ubuntu 12.04 server to 14.04, taking care to preserve our existing configurations.

Warning: As with almost any upgrade between major releases of an operating system, this process carries an inherent risk of failure, data loss, or broken software configuration. Comprehensive backups and extensive testing are strongly advised.

To avoid these problems, when possible, we...

One of the strengths of Ubuntu is its stability. Each bit of software included inside releases are vigorously tested. They are essentially “snapshots” in time. Everything stays stable. This method has proven to be very effective. Ubuntu is used heavily in work and production environments as a result of this. This is great for most users, but for advanced users looking to get the latest and the greatest, this can be a bit of a drawback.

For the most part, new software can be added to Ubuntu with the help of personal package archives (PPAs). These methods of distribution can cut through Ubuntu’s “snapshot” method and allow newer, more current software to be easily delivered. Power users often turn to this to make their installations more “bleeding edge” than before.

Still, this is not very true for every aspect of Ubuntu, especially when it comes to the Linux kernel. This is because each version of Ubuntu ships with a frozen kernel. This means that during development,...

Upgrade Ubuntu 14.04 LTS to Ubuntu 16.04 LTS. Ubuntu is widely used Linux operating system used for Desktop as well as Server edition. Ubuntu providing two types of releases Standard release and Long Term Support (LTS) release. Ubuntu provides support for standard releases for approx 1 year while Long Term Support is useful for approx 5 years.

Ubuntu Desktop uses can upgrade to any release but for Server editions we recommend to use LTS release and always upgrade to LTS release only.

A new Ubuntu 16.04 LTS release is available to upgrade. Every Ubuntu (Desktop + Server) users can upgrade your systems to this new release. As you are currently using Ubuntu 14.04 LTS so we recommend you to upgrade to Ubuntu 16.04 LTS.

Upgrade an existing Ubuntu installation to 18.04 Bionic Beaver


You need an existing Ubuntu 16.04 LTS or 17.10 install.


An existing Ubuntu 16.04 LTS or 17.10 install with root privileges.




# - requires given linux commands to be executed with root privileges either directly as a root user or by use of sudo command $ - requires given linux commands to be executed as a regular non-privileged user


The latest Ubuntu release, 18.04, marks an opportunity for both LTS users and people on the previous 17.10 release to update Ubuntu and take advantage of the latest features. Thanks to Debian's upgrade process, it should be relatively simple to either upgrade Ubuntu 16.04 to 18.04 (both LTS) or to upgrade Ubuntu 17.10 to 18.04 LTS Bionic Beaver.

Long-term Support for Ubuntu 14.04 also means that you can get the latest stable kernel and graphics as well. Importantly, these remain supported by the kernel and graphics teams and you’ll receive a regular supply of updates for 9 months.

Remember – you’ll need to update just before 9 months to get the next LTS kernel and graphics before support is officially withdrawn. If this sounds like too much hassle – best stick with the 3.13 kernel and graphics – they remain supported for 5 years!

The community wiki page describes how to install the latest kernel and graphics – but you need to be very careful.

For me the instructions meant that I could have destroyed my wine + pipelight installation but more importantly, bcmwl wireless could have been left in a broken state because the bcmwl package has not yet been backported.

The wiki page stated that to upgrade the kernel and graphics you use the following:

Recently, I'd noticed some shenanigans going on with my installation of Elementary OS Freya. Bluetooth had become erratic and certain apps had started to bog down. To some, Bluetooth might not be such a deal breaker, but I rely on both a Bluetooth mouse and Bluetooth trackpad for my desktop, so this was starting to become a problem.

It turns out that the issues were stemming from the 3.16 kernel. Considering that the Linux 4.0 kernel has a completely new method of handling the likes of touchpads, I thought it might be a good idea to undertake the upgrade.

Now, if you remember, I had similar dealings with this when I upgraded my desktop from Ubuntu 14.10 to 15.04 (see my post "Tweak your touchpad to taste in Linux"), but since stepping away from Ubuntu, I assumed the issues that caused me to need to tweak the touchpad in the first place were gone.

Hello, old friend.

So, in order to get around the problems, I found myself having to upgrade the Elementary...

The latest Canonical announcement lets Ubuntu 16.04 LTS users to install Linux kernel 4.10. The distribution is originally powered by the kernel 4.4.

Users were given an option of installing Linux kernel 4.8 on Ubuntu 16.04 following the release of Ubuntu 16.10 (Yakkety Yak) in last October. But with Ubuntu 16.04.2 LTS, users can install a newer kernel from Ubuntu 17.04 (Zesty Zapus).

Linux kernel 4.10 is quite better in terms of performance over the original kernel 4.4. You need to install the linux-image-generic-hwe-16.04 package from Canonical repositories to install the new kernel version. It fixes a list of 40 security issues alongside enhancing the performance.

New update in pipeline

In addition the manual update process, Canonical is scheduled to launch the next point release Ubuntu 16.04.3 LTS on August 3 this year. This next point release will be shipped with Linux kernel 4.10 by default.

Warning: An earlier version of this guide included mention of Ubuntu 14.04 systems. While an upgrade from 14.04 may successfully complete, upgrades between LTS releases are not enabled by default until the first point release, and it is recommended to wait until the 16.04.1 point release to upgrade. On DigitalOcean systems, an upgraded Ubuntu 14.04 system will be left with an older kernel which may not be upgradeable for some time.

The Ubuntu operating system’s next Long Term Support release, version 16.04 (Xenial Xerus), is due to be released on April 21, 2016.

Although it hasn’t yet been released at the time of this writing, it’s already possible to upgrade a 15.10 system to the development version of 16.04. This may be useful for testing both the upgrade process and the features of 16.04 itself in advance of the official release date.
