sudo apt search linux-headersĪfter finding the appropriate package, we can install it as follows. We can also search for specific Linux headers using the following command. Sudo apt-get install –y linux-headers-$(uname -r) We can manually verify the Kernel version using the following command. In the first command, the uname -r parameter fetches the installed Kernel version on the system. 1# sudo apt-get install –y linux-headers-$(uname -r) When the upgrading process completes, reboot the system for the changes to take effect.Īfter rebooting the system, we can install the Linux-headers package using any of the following commands.

Note: The sudo apt-get upgrade command only upgrades the newest available versions of the installed packages, whereas the sudo apt-get dist-upgrade also removes the obsolete packages from the system. sudo apt-get updateĪfter updating the packages list, we can download and install the available updates using the dist-upgrade command. This can be achieved with the following command.

First, we need to update the packages list to get information about the latest available versions of the installed packages and dependencies.

How to Automatically Install Linux Headers?īefore installing Linux headers, it is important to upgrade the available packages and remove the obsolete ones. This interface is provided by the Linux headers. Therefore, an interface is required between the protected space and the userspace. The space used by other applications is known as userspace. The protected Kernel space is inaccessible by other applications. The space reserved for Kernel code execution is called the Protected Kernel Space. Since Kernel itself is a program (mostly developed in C language), it also requires memory space to execute the code. Similarly, the Kernel is responsible for allocating and de-allocating the memory resources to the applications.

For instance, when multiple processes run on an operating system, the Kernel provides uniform resource access to all the running processes. It controls various activities including task management, memory management, disk management, etc. When an OS boots Kernel loads after boot loader. The kernel is the core program in any Operating System (OS). The Linux-headers is a package that provides an interface between Kernel internal components, and between Kernel and external memory resources. The concept of Linux headers is similar to these header files. Instead of reproducing the same code in each source file, separate files are introduced as an interface between the source files. Many source files need common declarations and functions to operate. A computer or software program contains multiple source files.
