How to update kernel to the latest mainline version without any Distro-upgrade?

Question

Currently I'm running Linux-3.0 and I want to update it to Linux-3.3.1 the latest stable kernel release as mentioned at http://www.kernel.org. Can I update to 3.3.1 in Ubuntu without any risk of crashes? I'm updating my kernel regularly as provided by the Update Manager..Currently I have Linux-3.0.0.17..Can I update?

NOTE:

The latest kernel version any user is supposed to use in Ubuntu is updated automatically via the Update Manager, so no action is normally required by user regarding kernel upgrades. What the question author is referring to is mainline kernel, see: Should I upgrade to the "mainline" kernels?

Answer 1

I created this script kernel-upgrade.sh that downloads and installs a selected kernel from http://kernel.ubuntu.com/~kernel-ppa/mainline

TMP=/var/tmp/kernel
mkdir -p $TMP && cd $TMP  
rm $TMP/*
F=v4.15-rc7
V=4.15.0-041500rc7
R=$(wget -qO - http://kernel.ubuntu.com/~kernel-ppa/mainline/$F/0005-debian-changelog.patch|grep +linux |head -n1|cut -d\( -f2|cut -d\) -f1|cut -d\. -f4)
B=$V.$R
URL=http://kernel.ubuntu.com/~kernel-ppa/mainline
set -x
wget $URL/$F/linux-headers-$V-generic_${B}_amd64.deb
wget $URL/$F/linux-headers-${V}_${B}_all.deb
wget $URL/$F/linux-image-$V-generic_${B}_amd64.deb
sudo dpkg -i linux-*.deb 
sudo update-grub
: "now enter: sudo reboot now"

In case Ubuntu doesn't start with the new kernel, you can select "advanced settings" in your grub menu and select to start the last running kernel there.

Answer 2

None of the above answers satisfied my problem of manually update the kernel to the latest stable version. (My current laptop is very sensitive to RCs, Dell XPS 9365).

I created a shell script that searches for more recent kernel versions and shows them as options to be installed. You can give it a try, it's on github, please be sure to read the README.

Answer 3

You could always do the following:

apt-cache search linux-image

Pick the one you want and then do:

sudo apt-get install linux-image-your_version_choice linux-headers-your_version_choice linux-image-extra-your_version_choice

Answer 4

late but new answer.

I will add some more information in my answer.Now my old kernel was linux-headers-4.8.0-53.To find out which kernel you have type uname -rin terminal.Now type this command to get list of available kernels.

apt-cache search linux-image

this will give you a very big output.Now chose one of them that you want to install and install it by following commands(Don't type these commands like this,replace the word kernal_version with the kernel version which you wish to install)

sudo apt-get install linux-image-kernal_version
sudo apt-get install linux-image-extra-kernal_version
sudo apt-get install linux-headers-kernal_version

Now in my case i choose linux-image-4.10.0-22-generic so my command will look like this

sudo apt-get install linux-image-4.10.0-22-generic 
sudo apt-get install linux-image-extra-4.10.0-22-generic
sudo apt-get install linux-headers-4.10.0-22-generic

now in the end remove old kernel by command

sudo apt-get autoremove

Now when I first did it, I Don't know is it my hardware problem or because of removing the old kernel,but my laptop shows me black screen which happens to my laptop sometimes.Thus I remove it's battery and rebooted and typed the command.Also i don't suffer from my black screen issue any more.

uname -r

and it gives me

linux-image-4.10.0-22-generic

which means kernel is updated.

If you don't want to go through the hassle to manually upgrade the kernel you can try UUKU. Works fine even on Ubuntu derivatives like elementory, mint.

I used it to fix my WiFi issue as sometimes some new hardware won't be detected by old kernel. Other than hardware driver update I don't find the need to upgrade kernel. New kernels do have security and slight performance upgrade but also have tendency to break things like your VM.

sudo apt-add-repository -y ppa:teejee2008/ppa
sudo apt-get update
sudo apt-get install ukuu
ukuu-gtk

Answer 6

Run the following Terminal commands to install a new Ubuntu mainline kernel.

sudo apt-get update
sudo apt-get install python-bs4
cd /tmp
rm -rf medigeek-kmp*
wget https://github.com/medigeek/kmp-downloader/tarball/master -O kmpd.tar.gz
tar xzf kmpd.tar.gz
cd medigeek-*
python kmpd.py -d

The script is hosted at Github. Just press Enter instead of a number if you get stuck on a certain question in the Python script.

Answer 7

Contrary to some answers here Ubuntu releases the new kernel within a day or two of the main kernel team. I used to upgrade the hard way like some of the answers here suggest and all of them on the internet suggest but I found and easier way.

Finding the latest kernel

Go to (kernel.ubuntu.com - Kernel PPA Mainline) and press the End key:

Now click on the link 4.9.8 (or a newer one if available when you read this) and the following appears:

Note the links with the black airbrush marks. These are the three we will download for Ubuntu 16.04 64-Bit using Intel or AMD processors.

Installing using Terminal

Open a terminal session with ctrl+Alt+T and use:

cd Downloads # Assuming this is your browser download directory
rm *.deb     # This erases all *.deb files, ensure only old ones are here

Now switch back to the download screen above and single-click on all three of the .deb kernel downloads. After downloads complete (you'll see status in your browser) switch back to terminal session and use:

sudo dpkg -i *.deb
rm *.deb
sudo reboot

Voila! - you are running the latest kernel when the first option in grub boot menu is selected. Your older kernel versions are still available under grub's Advanced Options menu.

After installing the newest kernel a dozen times you will ask the question "How do I remove older kernel versions?" and you will find those answers here in Ask Ubuntu.

Answer 8

I wrote a script and always will be up to date.

ukupgrade: Ubuntu Kernel Upgrade

• Open your favorite terminal and run the follwing commands

• Give executable permission to file

  chmod +x ./ukupgrade

• Call the script

  ./ukupgrade

Answer 9

The simplest set of instructions I always used for kernel upgrade / downgrade are by ubuntuforums.org user by the name of lykwydchykyn (url modified by me for this post):

1. Go here: http://kernel.ubuntu.com/~kernel-ppa/mainline/

2. Download 3 (maybe 4) debs to a folder somewhere:

   linux-headers-VERSION-NUMBER_all.deb
   linux-headers-VERSION-NUMBER_amd64.deb
   linux-image-VERSION-NUMBER_amd64.deb
   linux-image-extra-VERSION-NUMBER_amd64.deb   # if available
   

3. Install the debs with whatever package manager front-end you use (is gdebi still around?), or use these commands:

   cd /path/to/folder/where/you/put/the/debs
   sudo dpkg -i *.deb

Answer 10

There is a much simpler way of doing this, and it's the way I use. Simply download the Ubuntu Mainline Kernel Updater script and run it from a terminal. It will download the .deb's for you, install the new kernel, and optionally remove the old one (not recommended) then optionally reboot.

Example output (copied from my terminal):

evilsupahfly@the-black-beast:~$ sudo KernelUpdateChecker -no-rc -r utopic

Answer 11

My answer is, YES you can. The stable release was 3.4, but in this tutorial i use 3.3.1.

Ubuntu (32-bit) Generic PAE:

Run the following commands:

mkdir kernel\ v3.3.1-precise && cd kernel\ v3.3.1-precise
wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.3.1-precise/linux-headers-3.3.1-030301-generic-pae_3.3.1-030301.201204021435_i386.deb
wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.3.1-precise/linux-headers-3.3.1-030301_3.3.1-030301.201204021435_all.deb
wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.3.1-precise/linux-image-3.3.1-030301-generic-pae_3.3.1-030301.201204021435_i386.deb
sudo dpkg -i linux-*.deb 
sudo update-grub
sudo reboot now

Ubuntu (64-bit):

Run the following commands:

mkdir kernel\ v3.3.1-precise && cd kernel\ v3.3.1-precise
wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.3.1-precise/linux-headers-3.3.1-030301-generic_3.3.1-030301.201204021435_amd64.deb
wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.3.1-precise/linux-headers-3.3.1-030301_3.3.1-030301.201204021435_all.deb
wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.3.1-precise/linux-image-3.3.1-030301-generic_3.3.1-030301.201204021435_amd64.deb
sudo dpkg -i linux-*.deb 
sudo update-grub
sudo reboot now

Enjoy!

Answer 12

Another option is to try customized and optimized builds, such as this i3/i5/i7 optimized 3.2.1 kernel for Ubuntu:

DuoPetalFlower, My Experiments with Linux - 3.2.1 kernel

He also has Intel atom optimized builds which can work quite well if you're trying to squeeze every last ounce of performance out of a netbook.

There are other kernels like Liquorix that claim to be better optimized for desktop performance.

Though not recommended by some, you can often run official kernels from later versions of Ubuntu without issues. I'm currently running the 3.3.3 precise kernel on oneiric and my machine works better than ever. Performance & battery life increased, while temperatures dropped a few degrees. My issue of a black screen when resuming from standby has also disappeared. Though I personally haven't had issues from using newer kernels, you will find some people who are strongly opposed to doing this.

Answer 13

As you've seen, Ubuntu does provide versions of the Linux kernel, but not always as fast as they are released upstream, you can always compile the 3.3.1 kernel yourself, but that may be more effort than you were looking for. If not, search around and I'm sure you'll find a tutorial you can follow such as this one. (note that I haven't checked that one thoroughly so be wary as kernels are dangerous beasts)
