This post will help you to remove any unused or old Linux kernel from your Ubuntu Linux operating system. It is also good move to remove old or unused Kernels from Linux as it occupies more space in /boot partition on Ubuntu.

How To Remove Kernel In Ubuntu | Delete Old Or Unused Kernal

DISCLAIMER: The following process of Kernels deletion from your systems might affect your Linux. Please be careful before your remove old or unused kernel.

Some of the things that you should do before removing your old or unused kernels are:

• Backup your files or any important documents.
• Note down the version of your Linux Kernel.

Linux kernels and their associated files are stored under the /boot directory and the Kernel modules are stored in /lib/modules directory of your system. The Linux kernel files names starting with “vmlinuz-” or “vmlinuz.” and end with the version number.

Run the following  commands to check all installed Linux Kernels in Debian, Ubuntu and its derivatives:

dpkg --list | grep linux-image

You will see the output with the list of installed Linux kernel in your Linux operating systems.

rc  linux-image-5.15.0-25-generic              5.15.0-25.25                            amd64        Signed kernel image generic
ii  linux-image-5.15.0-41-generic              5.15.0-41.44                            amd64        Signed kernel image generic

In above output, “rc” stands for “removed, but the configuration files are still present and  “ii” stands for “installed, and successfully installed.

Run the following command to remove old and unused Kernels automatically. sudo apt-get autoremove --purge command scans Linux system for packages that were installed as dependencies but are no longer needed. It also removes those packages and their associated configuration files. It helps to free up disk space and cleaning up the system by removing unnecessary packages.

sudo apt-get autoremove --purge

How to Purge Old Unused Kernels in Debian-based Systems

Run the following command to remove old unused Linux Kernels and keep only the currently running Linux Kernel.

$ echo $(dpkg --list | grep linux-image | awk '{ print $2 }' | sort -V | sed -n '/'`uname -r`'/q;p') $(dpkg --list | grep linux-headers | awk '{ print $2 }' | sort -V | sed -n '/'"$(uname -r | sed "s/\([0-9.-]*\)-\([^0-9]\+\)/\1/")"'/q;p') | xargs sudo apt-get -y purge

Or,

Run the following command to remove old or unused Linux Kernel and keep only the currently running Linux Kernel.

$ sudo apt-get purge $(for tag in "linux-image" "linux-headers"; do dpkg-query -W -f'${Package}\n' "$tag-[0-9]*.[0-9]*.[0-9]*" | sort -V | awk 'index($0,c){exit} //' c=$(uname -r | cut -d- -f1,2); done)

The most recent stable kernel is Linux 6.15, which Ubuntu users can install on their computers by using the official Ubuntu Mainline Kernel PPA archive. Here’s a brief guide on using the GUI and CLI to accomplish it. With new features like Rust support for hrtimer and ARMv7, a new setcpuid= boot parameter for x86 CPUs, support for sched_ext to count and report internal events, improvements to the x86 Intel and AMD PMU, nested virtualization support for VGICv3 on ARM, and more, Linux kernel 6.15 was released on May 25th, 2025.

How to Install Linux Kernel 6.15 on Ubuntu 25.04 and Ubuntu 24.10

The preferred and the most easiest way to install Linux kernel 6.15 on your Ubuntu is by using a graphical tool called Mainline Kernels. You can easily install it from this PPA by running the following commands in the Terminal.

Method 1: Install Mainline Kernels Tool In Ubuntu

Run the following commands.

sudo add-apt-repository ppa:cappelikan/ppa
sudo apt update && sudo apt full-upgrade
sudo apt install -y mainline

Once the Mainline Kernels tool is installed, you can check the availability of all kernel versions from Canonical’s Mainline Kernel PPA. The tool will quickly  archive and will list Linux kernel 6.15 at the top of the list. Click on the “6.15” entry to select it and then click on the big “Install” button. Wait for the installation to complete and then reboot your computer.

Method 2: Install Linux kernel 6.15 on Ubuntu via CLI

This one is for the pro users or those users who love to do things on Ubuntu via Command line.  In this process, you need to manually download  and install the Linux 6.15 kernel packages from the official Ubuntu mainline kernel PPA archive  for your specific architecture (64-bit (amd64), AArch64 (ARM64), ARMhf, PowerPC 64-bit Little Endian (ppc64el), or IBM System z (s390x))

linux-headers-6.15.0-061500-generic_6.15.0-061500.202505260036_amd64.deb
linux-headers-6.15.0-061500_6.15.0-061500.202505260036_all.deb
linux-image-unsigned-6.15.0-061500-generic_6.15.0-061500.202505260036_amd64.deb
linux-modules-6.15.0-061500-generic_6.15.0-061500.202505260036_amd64.deb

Once you have downloaded all the kernel packages in the respective folder, you need to install them all at once by running the sudo dpkg -i *.deb command.

How to revert baack Ubuntu’s default kernel

This steps is important if you experience any issues running Linux kernel 6.15 and you want to go back to Ubuntu’s default kernel. You need to press the Esc key when your computer boots to view the boot menu, then access the “Advanced options” boot entry and select a different kernel version from the list of available kernels. You won’t have any issues onward as it revert back to the default kernel or any other working kernel that you have selected.

These days, you can find the most of the drivers in Ubuntu 24.04 LTS. There are basically two type of driver in Linux. Open and closed source driver. Proprietary driver falls in the closed source driver category. Drivers like Nvidia drivers falls in this category. Ubuntu itself identifies and installs drivers on your system but some hardware still needs additional drivers to be installed  In this Ubuntu 24.04 LTS tutorial post, we will show you the two different methods to install Proprietary drivers in Ubuntu.

This tutorial is for those people who wants to bring the vibes of Kali Linux on Ubuntu by converting traditional terminal of Ubuntu to Kali Linux terminal.  Ubuntu is popular among the regular users while Kali Linux is mostly used by security enthusiast.

Make Ubuntu Terminal Look Like Kali Linux In 2025

We will be installing  zsh shell, zshell plugins and some additional tools in your Ubuntu so that we can convert terminal. The Z shell is an interactive shell that incorporates many features like bash, fish, dash, and ksh. 

Installing ZSH on Ubuntu 24.04 LTS

Run the following command to install ZSH on Ubuntu-based operating systems.

sudo apt update

sudo apt install zsh

After installation is complete,  run the zsh command to switch from the bash prompt. You will see a z shell configuration prompt where you need to select option “0” from the prompt and then hit enter.

Install Z shell plugins by running following commands.

sudo apt install zsh-syntax-highlighting zsh-autosuggestions

Run the following command to change your default login shell to the z shell.

chsh -s /bin/zsh

Modifying the zshrc file

Tweak the zshrc file to customize. It is located in your home directory (~/.zshrc). zshrc is a hidden file so you need to configure your system to see the hidden file. Sometimes the file may not be available, so you must create or delete it if it is already available.

To delete the file run the following command:

rm ~/.zshrc

To create a new file simply run this command:

touch ~/.zshrc

After successfully creating the .zshrc file, open it with your preferred text editor and then you need to copy and paste the following content into your .zshrc file, and save.

# ~/.zshrc file for zsh interactive shells.

# see /usr/share/doc/zsh/examples/zshrc for examples

setopt autocd # change directory just by typing its name

#setopt correct # auto correct mistakes

setopt interactivecomments # allow comments in interactive mode

setopt magicequalsubst # enable filename expansion for arguments of the form ‘anything=expression’

setopt nonomatch # hide error message if there is no match for the pattern

To make the changes take effect, run the following command:

$ source .zshrc
$ . .zshrc

Now, Download color schemes and themes with the following command:

git clone https://github.com/linuxopsys/ubuntu-to-kali-terminal.git

cd ubuntu-to-kali-terminal

Now extract the compressed files:

tar -xvf color-schemes.tar
tar -xvf kali-dark-theme.tar

You will notice a new directory name “usr” in your current working directory.

Now you need to remove the qtermwidget5 directory located in the /usr/share directory and replace it with one from the extracted tar file.

sudo rm -rf /usr/share/qtermwidget5
sudo mv -f usr/share/qtermwidget5 /usr/share

Now its time to Change Qterminal settings

• Open your Qterminal preferences
• Change the color scheme to Kali-Dark and then press the Apply button
• At the bottom of your terminal’s Appearance settings, Adjust the “Application transparency” from “0%” to “5%,”
• Click apply for the changes to take effect.

Now, it’s time to change the Ubuntu theme. Run the following command to move the Kali-Dark directory from the directory you extracted to /usr/share/themes directory.

sudo mv -f usr/share/themes/Kali-Dark /usr/share/themes

Now, you can tweak your setting by going to the gnome-tweaks by running the following command:

gnome-tweaks

Meanwhile, If you have Gnome Tweak Tool installed in Ubuntu then go through the following article:

Ubuntu is one of the most popular Linux-based operating systems. We can say this is one who is leading the race from the side of Linux in the OS market dominated by Windows. Ubuntu 22.04 LTS is the latest version of Ubuntu Linux and Windows 11 is the latest version of the operating system from Microsoft.

It will be interesting to see the performance of these two operating systems in the market. Meanwhile, In this tutorial post, we are going to install Ubuntu 22.04 LTS on Windows 11. It’s not about installing Ubuntu in any virtual desktop environment as we will install Ubuntu on Windows 11 and it will be with the help of Windows Subsystem for Linux (WSL)

Install Ubuntu 22.04 LTS On Windows 11

Windows Subsystem for Linux (WSL) allows you to install Ubuntu on your Windows machine without any complications. At first, you need to enable and install WSL on Windows 11. Before that, you need to verify the Virtual Platform feature. For this,

1. Search for Windows features.
2. Open the control panel and scroll down to Virtual Machine Platform and select it.
3. After installation of the Virtual Machine Platform component,  restart Windows 11.

Install WSL on Windows 11

You can easily install the WSL application from the Microsoft Store by opening it and searching for the Windows subsystem or you can install it by executing the following command in the Powershell.

wsl --install

Download Ubuntu on Windows 11

Open Microsoft Store and search for Ubuntu and install it by clicking on Get button.

Wait for a while and you are ready to use Ubuntu on Windows 11. Now, you will need to create a username and password for the newly installed Ubuntu operating system.

On Windows 11, WSL comes with WSLg that allows you to run graphical Linux applications.

To check that you have the latest package lists, type:

sudo apt update

Then, execute the following command on Ubuntu to start with some basic X11 applications:

sudo apt install x11-apps

Run the following command to run the xeyes, a “follow the mouse” application:

xeyes &

Note: Some of the other Linux operating systems that you can install on Windows 11 with WSL are Debian, Fedora, Kali, Alpine, and Linux Suse.

Meanwhile, if you want to change the Linux operating system on Windows 11 then run the following command.

wsl --install -d <Distribution Name>. Replace <Distribution Name> with the name of the Linux operating system, you would like to install.

Git is a free and open-source distributed version control system. Here, You can find the step by step guide to install Git on Ubuntu 22.04 LTS.

How To Install Git On Ubuntu 22.04 LTS In 2024

Make sure that all of the packages installed on Ubuntu 22.04 are up to date before beginning the Git installation on Ubuntu. To find out if the packages are current, run the following command.
