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.).

    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.

  • Note: this doesn't put them in the GCC include path, you still need -I. Aug 8, 2015 at 7:34

    Note: For this to work, the line appropriate deb-src line must be present in /etc/apt/sources.list.

You can just type:

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) Apr 28, 2015 at 16:00

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This should cover another problem when: the currently running kernel is obsolete, meaning it's not in the repository anymore neither its headers.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.

    None of the other solutions worked for me when trying to install a driver. Thanks you. Jan 5, 2016 at 3:33

    an almost equivalent for debian is called linux-headers-amd64 (for amd64 systems, obviously)

    Amazing, linux-headers-amd64 did the job for me for my Gitlab pipelines! The linux-headers-$(uname -r) did not work though. Voting up.

Or if you have aptitude installed: sudo aptitude install linux-headers-$(uname -r)

    Essentially the same thing.

these commands should work:

sudo apt-get dist-upgrade -y
systemctl reboot
sudo apt-get install linux-headers-$(uname -r)
sudo apt-get upgrade linux-headers-$(uname -r)

  • He is just asking how to install headers, why would you recommend upgrading the distribution? Do not follow these steps if you just want to download the headers.
