Install Kernel Headers and Required Build Tools

A successful installation of kernel headers on AlmaLinux requires kernel headers and other build tools. Thus, be sure to install the kernel headers and required build tools. Some of the required tools are available on the EPEL repos, hence begin by installing the EPEL repos on AlmaLinux

dnf install epel-release -y

Next, install the kernel headers and build tools by executing the command below;

dnf update --refresh -y
dnf install dkms kernel-devel kernel-headers gcc make bzip2 perl elfutils-libelf-devel

Next, ensure that the installed version of kernel-devel matches the version of your running kernel. You can verify by running the commands below.

rpm -q kernel-develuname -r
compare kernel version numbers

If they do not match, update your kernel by running;

dnf update kernel-*

Next, reboot the system;

sudo systemctl reboot -i

and verify the kernel versions again.

rpm -q kernel-develuname -r
compare kernel version numbers
