Linux header install ubuntu

How do I install kernel header files?

You should be able to install the kernel header files for the currently running kernel by running the following in a terminal:

sudo apt-get install linux-headers-$(uname -r) 

In general, the kernel header packages are named linux-header-* where «*» indicates the version & variant (generic, server, etc.).

hey thanks but could you tell me what does generic, server, etc means i want to write (kernel driver)

This won’t install the headers for future updates automatically and you’ll have to re-run this command every time. Therefore, it’s recommended to install the metapackage instead, as described in another answer.

sudo apt-get install linux-headers-generic 

if you are on a Desktop installation. The apt-get will solve the dependencies and install the correct version of kernel headers.

In Debian Wheezy I get the error message «Package linux-headers-generic is not available, but is referred to by another package. [. ] E: Package ‘linux-headers-generic’ has no installation candidate»

@IQAndreas the linux-headers-generic package is ubuntu specific. On Debian you should use sudo apt-get install linux-headers-$(uname -r)

I have linux-headers-generic installed on 18.04 but still don’t have the headers for the newest and current kernel version. Maybe it’s just a bug with this version, I’ve compiled kernel modules in earlier versions so I must’ve had the correct headers back then.

Case of Obsolete kernel package

This should cover another problem when: the currently running kernel is obsolete, meaning it’s not in the repository anymore neither its headers. So the best thing to do is to update the kernel to last version in the repository.

linux-generic is a meta package to keep current version of the kernel & its headers:

sudo apt-get update sudo apt-get install linux-generic 

Note: Depending on your Ubuntu edition, See if you need linux-lowlatency (Ubuntu Studio), linux-signed-generic or linux-virtual .

How to Install Kernel Headers in Ubuntu and Debian

In our last article, we have explained how to install kernel headers in CentOS 7. Kernel Headers contain the C header files for the Linux kernel, which offers the various function and structure definitions required when compiling any code that interfaces with the kernel, such as kernel modules or device drivers and some user programs.

It is very important to note that the kernel headers package you install should match with the currently installed kernel version on your system. If your kernel version ships with the default distribution installation or you have upgraded your Kernel using dpkg or apt package manager from the Ubuntu or Debian base repositories, then you must install matching kernel headers using package manager only. And if you’ve compiled kernel from sources, you must also install kernel headers from sources.

In this article, we will explain how to install Kernel Headers in Ubuntu and Debian Linux distributions using default package manager.

Install Kernel Headers in Ubuntu and Debian

First check your installed kernel version as well as kernel header package that matches your kernel version using following commands.

$ uname -r $ apt search linux-headers-$(uname -r)

On Debian, Ubuntu and their derivatives, all kernel header files can be found under /usr/src directory. You can check if the matching kernel headers for your kernel version are already installed on your system using the following command.

$ ls -l /usr/src/linux-headers-$(uname -r)

From the above output, it’s clear that the matching kernel header directory doesn’t exist, meaning the package is not yet installed.

Before you can install the appropriate kernel headers, update your packages index, in order to grab information about the latest package releases, using the following command.

Then run the following command that follows to install the Linux Kernel headers package for your kernel version.

$ sudo apt install linux-headers-$(uname -r)

Next, check if the matching kernel headers have been installed on your system using the following command

$ ls -l /usr/src/linux-headers-$(uname -r)

That’s all! In this article, we have explained how to install kernel headers in Ubuntu and Debian Linux and other distributions in the Debian family tree.

Always keep in mind that to compile a kernel module, you will need the Linux kernel headers. If you have any quires, or thoughts to share, use the comment form below to reach us.

Как установить заголовки ядра в Ubuntu и Debian

В нашей последней статье мы объяснили, как установить заголовки ядра в CentOS 7. Заголовки ядра содержат файлы заголовков C для ядра Linux, которые предлагают различные функции и структуру. определения, необходимые при компиляции любого кода, взаимодействующего с ядром, например, модулей ядра или драйверов устройств и некоторых пользовательских программ.

Очень важно отметить, что устанавливаемый вами пакет заголовков ядра должен совпадать с текущей установленной версией ядра в вашей системе. Если ваша версия ядра поставляется с установкой дистрибутива по умолчанию или вы обновили ядро с помощью dpkg или диспетчера пакетов apt из базовых репозиториев Ubuntu или Debian, то вы должны установить соответствующие заголовки ядра только с помощью диспетчера пакетов. И если вы скомпилировали ядро из исходников, вы также должны установить заголовки ядра из исходников.

В этой статье мы объясним, как установить Kernel Headers в дистрибутивах Ubuntu и Debian Linux с помощью диспетчера пакетов по умолчанию.

Установите заголовки ядра в Ubuntu и Debian

Сначала проверьте установленную версию ядра, а также пакет заголовка ядра, который соответствует вашей версии ядра, используя следующие команды.

$ uname -r $ apt search linux-headers-$(uname -r)

В Debian, Ubuntu и их производных все заголовочные файлы ядра можно найти в каталоге /usr/src. Вы можете проверить, установлены ли в вашей системе соответствующие заголовки ядра для вашей версии ядра, используя следующую команду.

$ ls -l /usr/src/linux-headers-$(uname -r)

Из приведенного выше вывода ясно, что соответствующий каталог заголовков ядра не существует, а это означает, что пакет еще не установлен.

Прежде чем вы сможете установить соответствующие заголовки ядра, обновите индекс пакетов, чтобы получить информацию о последних выпусках пакетов, используя следующую команду.

Затем выполните следующую команду, чтобы установить пакет заголовков ядра Linux для вашей версии ядра.

$ sudo apt install linux-headers-$(uname -r)

Затем проверьте, установлены ли в вашей системе соответствующие заголовки ядра, используя следующую команду.

$ ls -l /usr/src/linux-headers-$(uname -r)

Вот и все! В этой статье мы объяснили, как установить заголовки ядра в Ubuntu и Debian Linux и других дистрибутивах в генеалогическом дереве Debian.

Всегда помните, что для компиляции модуля ядра вам понадобятся заголовки ядра Linux. Если у вас есть какие-либо вопросы или мысли, которыми вы хотите поделиться, используйте форму комментариев ниже, чтобы связаться с нами.

How To Install Kernel Headers on Ubuntu

In this tutorial, we will show you how to install Kernel Headers on Ubuntu. For those of you who didn’t know, Kernel headers are files that provide the necessary information for building kernel modules, which are programs that can be loaded into the kernel at runtime to extend its functionality. These headers contain information about the internal data structures and function calls used by the kernel, and they are required for building out-of-tree kernel modules, which are modules that are not included in the official kernel source code.

This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘ sudo ‘ to the commands to get root privileges. I will show you the step-by-step installation of the Kernel Headers on Ubuntu Linux. You can follow the same instructions for Ubuntu 22.04 and any other Debian-based distribution like Linux Mint, Elementary OS, Pop!_OS, and more as well.

Prerequisites

• A server running one of the following operating systems: Ubuntu 22.04, 20.04, and any other Debian-based distribution like Linux Mint.
• It’s recommended that you use a fresh OS install to prevent any potential issues.
• SSH access to the server (or just open Terminal if you’re on a desktop).
• An active internet connection. You’ll need an internet connection to download the necessary packages and dependencies for Kernel Headers.
• A non-root sudo user or access to the root user . We recommend acting as a non-root sudo user , however, as you can harm your system if you’re not careful when acting as the root.

Install Kernel Headers on Ubuntu

Step 1. First, make sure that all your system packages are up-to-date by running the following apt commands in the terminal.

sudo apt update sudo apt upgrade

Step 2. Check the Current Linux Kernel.

Check the version of the kernel that is currently running on your system. You can do this by running the following command:

This will output the version of your kernel, for example:

Step 3. Installing Kernel Headers on Ubuntu.

Now run the following command that follows to install the Linux Kernel headers package for your kernel version:

sudo apt install linux-headers-$(uname -r)

You can verify that the kernel headers package has been installed by running the following command:

dpkg -l | grep linux-headers

Congratulations! You have successfully installed Kernel Headers. Thanks for using this tutorial for installing Kernel Headers on Ubuntu 22.04 LTS Jammy Jellyfish system. For additional help or useful information, we recommend you check the official Kernel website.
