Ubuntu 18 Kernel Version
UbuntuのOSバージョンとkernelバージョンの対応表を示す。 Ubuntu OSバージョンとkernelバージョン. Ubuntuのバージョンの歴史はこちらのWikipediaにまとまっている。(英語) Ubuntu version history - Wikipedia. Apr 20, 2019 Ubuntu 18.04 LTS is the current stable release of Canonical’s Linux operating system. It sports a lot of modern software thanks to backporting efforts.Despite this, users tend to get stuck on an aging version of the Linux kernel.
On Ubuntu operating systems, Ubuntu Kernel Update Utility (UKUU) is used to manage and update kernels. UKUU has a graphical and a command line frontend. It is really easy to use. In this article I will show you how to update the kernel version on Ubuntu 18.04 LTS codename Bionic Beaver using UKUU graphically and through the command line. Let’s get started.Checking the Currently Used Kernel Version
It’s a good idea to check the kernel version you’re using before performing kernel update. So you will be able to find out whether the kernel update worked.
Run the following command to check the kernel version you’re currently using:
As you can see, I am using kernel version 4.15 right now.
You can also see that I am using Ubuntu 18.04 Bionic Beaver. It’s in development as of this writing. But it should be released this month.
Installing UKUU
Ubuntu Kernel Update Utility also known as UKUU is not installed on Ubuntu 18.04 Bionic Beaver by default. It is not available in the official package repository as well. But it is available on UKUU PPA.
You can add UKUU PPA to your Ubuntu 18.04 machine with the following command:
Once you run the command, UKUU PPA should be added as you can see in the screenshot below.
As of Ubuntu 18.04, adding a PPA will also auto update the package repository cache. You won’t have to run sudo apt-get update manually anymore. It is a great feature to have.
Now you can install UKUU with the following command:
Press y and then press <Enter> to continue.
UKUU should be installed.
Upgrading the Kernel Graphically with UKUU
UKUU has a graphical application to update the kernel of Ubuntu 18.04 LTS operating system. To start UKKU Graphical User Interface (GUI), go to the Application Menu of Ubuntu 18.04 LTS, and search for ukuu. Now click on the UKUU icon as shown in the screenshot below.
You should see the following window. UKUU is generating a list of all the available kernels.
Once all the kernel information is downloaded, you should see the following window. As of this writing, the latest version of the kernel is 4.16. You can of course select any version you want.
I am going to install the latest version 4.16. So I will select that. Once you select your desired version, click on Install as marked blue in the screenshot below.
Now enter your password and click on Authenticate.
UKUU should start downloading and installing the new kernel.
Once it’s done, click on Close as marked in the screenshot below.
UKUU may give you a warning like this. Simply click on OK as this is the only thing you can do.
Now restart your computer for the changes to take effect.
Once your computer starts, you can run the following command to check the kernel version again:
As you can see from the screenshot below, the kernel is updated to the latest version.
Upgrading the Kernel using UKUU Command Line Utility
UKUU also has a command line utility which you can use to update the kernel of your Ubuntu operating system.
The reason why you might want to use the command line utility is that it is more stable that the GUI version of UKUU. Also if you’re using a headless Ubuntu Server or Ubuntu without graphical user interface, then you can’t use the UKUU GUI even if you want to without installing several gigabytes of GNOME dependencies, which is really unnecessary. You can use UKUU command line utility on Ubuntu headless servers.
I personally prefer the command line utility.
In this section I will show you how to use the UKUU command line utility to update the kernel of your Ubuntu 18.04 machine.
First run the following command to list all the available kernels:
UKKU should list all the available kernels as you can see in the screenshot below. I am going to install v4.16 kernel using UKUU.
Before you can install disable access control with the following command:
The access control should be disabled.
Now run the following command to install the desired kernel version (in my case v4.16):
UKUU should download and install the new kernel as you can see from the screenshot below.
The kernel v4.16 is installed.
Now restart your computer with the following command:
Once your computer starts, you can run the following command to check the currently used kernel version again:
As you can see the kernel is updated.
That’s how you upgrade the kernel on Ubuntu 18.04. Thanks for reading this article.
Want to find out which kernel versions installed on Ubuntu? For students and new users, this post might come in handy if they want to find out the running kernel version on Linux Ubuntu.
The kernel is the core of any operating systems… Whether Windows, Mac OS or Linux, it’s the most important and core component of the operating system.
The kernel sits between the hardware and the software. It manages hardware resources and relay information to the hardware on behalf of the software running on the computer.
For example, if a software application wants to use the CD Rom drive or play music to the sound card on the computer, the kernel will find the resource needed for the application to make that happen…
This brief tutorial shows students and new users how to find out which kernel version that is installed and running on Ubuntu 18.04 16.04 LTS
To get started, see the options below:
Option 1: Use uname Command
The most frequently used command to find out which version of Linux kernel currently installed and running is the uname command… Simply run the uname command followed by few options to get Linux kernel details…
To do that run the commands below:
uname -srm
That should output similar line as shown below:
Ubuntu Latest Kernel
That tells you that the kernel begin to a generic Linux distribution, a 64-bit with version # 4.18.0-25
Option 2: Use the hostnamectl Command
Another method to use to find out which kernel is installed and running with a bit of other information is the hostnamectl command… This command provides other details of the systems not available when using the first option above…
To use the hostnamectl command, simply type it:
Ubuntu 18 Change Kernel Version
hostnamectl
It should show and output as below
Again, same kernel, now you see its Architecture belongs to the 64-bit family…
Option 3: Use the /proc/version File
Both command option options above use the content of the /proc/version file to generate and display the kernel version…. While using the commands is a quicker option, you can simple the content of the version file by running the commands below:
Next tales of game 2018. Bandai Namco's 'Tales' series began in 1995 with Tales of Phantasia on the Super Famicom, PlayStation, and GBA, among other platforms, and was most recently seen a couple of years ago with.
cat /proc/version
Ubuntu 18 Lts Kernel Version
That displays the output as below:
The Kernel number 4.18.0-24 is identified as:
Sysmon Event ID 1. Source: Sysmon: Discussions on Event ID 1 Ask a question about this event. 1: Process creation. Free Tool for Windows Event Collection. Discussions on Event ID 1.

Go to Event Viewer, check the Windows security logs and see if any related entries, keywords: Event ID: 4616; Task Category: Security State Change were logged. This will help us to find out which process that was making the change. Windows Event Log Analysis Splunk App Build a great reporting interface using Splunk, one of the leaders in the Security Information and Event Management (SIEM) field, linking the collected Windows events to www.eventid.net. Oct 21, 2017 Well I was lucky enough to not have event id 1 showing up but as you can see from my first post I have event id 2 and 360. I feel the same about disabling the logging of certain events completely cause something actually important might get logged but don't have your hopes high that ms is gonna fix some of these issues asap.
- 4 – Kernel Version Number
- 18 – Major Revision Number
- 0 – Minor Revision Number
- 25 – Patch Number
- generic – Represents Generic Linux Distribution
These are some of the options available to you to find out Linux kernel versions… If you’re new or a student, these methods should come in handy.
That’s it!
Congratulations: You have successfully learned how to find which Linux kernel is installed and running on Ubuntu.
