Package repository with Linux vanilla kernels for Fedora

This page contains information about a set of repositories which contain RPM packages with Linux vanilla kernels built for Fedora. They are meant for users that want access new or in-development versions of Linux quickly and comfortably. The repo also is meant for users that want to check if a problem is specific to the Fedora kernel or present in upstream kernels as well.

How to use these repos

How to use, the quick (aka TLDR) version

Download the definitions for the Kernel vanilla repositories:

curl -s https://repos.fedorapeople.org/repos/thl/kernel-vanilla.repo | sudo tee /etc/yum.repos.d/kernel-vanilla.repo

Run this to get the latest development kernel:

sudo dnf --enablerepo=kernel-vanilla-mainline update

You don't want to run a development kernel and want the latest stable kernel instead? Then run this:

sudo dnf --enablerepo=kernel-vanilla-stable update

Reboot. That's it – at least most of the time, as sometimes additional steps are necessary:

Is UEFI Secure Boot active on your system (mokutil --sb-state will tell you)? Then you have to disable it in your BIOS Setup or via mokutil --disable-validation to run kernels from these repositories, as they are not signed with a key that a default Secure Boot setup considers trusted.

The newly installed kernel will normally get started by default. If that's not the case there is something fishy in your boot configuration. For example, if you start Fedora using a boot manger from a different distribution you'll have to boot into that one and update its boot loader configuration to pick up the newly installed kernel (this problem is not specific to the packages from this repo); in Ubuntu you do that by running update-grub.

Nothing gets installed by the "dnf update"-command? Then the version of the latest kernel package installed on your machine is higher than the version of the latest kernel packagers offered in the chosen kernel-vanilla repository.

Optionally run

sudo dnf config-manager --set-enabled kernel-vanilla-mainline

or

sudo dnf config-manager --set-enabled kernel-vanilla-stable

if you want to enable one of those repositories permanently – which is something you normally want, to make sure you get fixes for security problems that got fixed by the kernel developers.

Note: The above mentioned repositories are the two main ones. There are three more for other use cases. For details see below.

How to use, the verbose version

Configure the repositories

First download the repository definitions for DNF:

curl -s https://repos.fedorapeople.org/repos/thl/kernel-vanilla.repo | sudo tee /etc/yum.repos.d/kernel-vanilla.repo

This will install a repo file with following repos:

repository	description	target users	example versions
kernel-vanilla-mainline	the latest kernels from the Linux mainline series	those who want the latest mainline kernel	4.4, 4.5-rc0-git1, 4.5-rc1, 4.5-rc1-git2
kernel-vanilla-mainline-wo-mergew	the latest kernels from the Linux mainline series, except during the merge window, when it might contain the latest stable kernel.	those who want the latest mainline kernel, but want to avoid development versions from the merge window (like 4.5-rc0-git1) – that the phase in the development cycle when the bulk of changes get merged for a new kernel version	4.4, 4.4.1, 4.5-rc1, 4.5-rc1-git2
kernel-vanilla-stable	the latest non-development version from the mainline or stable kernel series	those who want the latest Linux stable kernel	4.4, 4.4.1
kernel-vanilla-stable-rc	the latest non-development version from the mainline or stable kernel series, but also kernels from the stable series that are about to get released	those who want to help testing new stable kernels. Note: repo is unmaintained ATM :-/	4.4, 4.4.1, 4.4.2-rc1
kernel-vanilla-fedora	contains a vanilla build of the latest kernel which Fedora currently ships or has in its update queue; most of the time this repository will contain the same kernels as kernel-vanilla-stable, except for times when Fedora hasn't yet jumped to the latest major version	those who want to check if a vanilla kernel shows the same bug or behavior as the Fedora kernel	4.4, 4.4.1

Decide yourself which one of those you want to use. The following examples assume you want to use the kernel-vanilla-mainline repository, hence adjust the commands if you want to use a different repository.

Install a kernel from the repository

Run this command to install the latest mainline kernel from the kernel vanilla repos:

sudo dnf --enablerepo=kernel-vanilla-mainline update

Alternatively you can permanently enable that repository to make DNF automatically install new kernel packages when updating the system:

sudo dnf config-manager --set-enabled kernel-vanilla-mainline
sudo dnf update

When you install a kernel from the repository for the first time DNF will ask you if you trust the public key that is used to verify the signature of the packages from the kernel vanilla repositories. It will look like this:

Retrieving key from https://repos.fedorapeople.org/repos/thl/RPM-GPG-KEY-knurd-kernel-vanilla
Importing GPG key 0x863625FA:
 Userid     : "Thorsten Leemhuis (Key for signing vanilla kernel rpms) <fedora@leemhuis.info>"
 Fingerprint: 7C71 B4C9 BF71 7876 635F 3205 4534 BEED 8636 25FA
 From       : https://repos.fedorapeople.org/repos/thl/RPM-GPG-KEY-knurd-kernel-vanilla
Is this ok [y/N]:

DNF will proceed once you acknowledge this.

Important notes

Please be aware that

none of the developers that maintain the Fedora kernel is involved in the maintenance of the kernel vanilla repos for Fedora
most systems work better and run in a more secure manner with the official Fedora kernels
if you don't know what above commands do then you likely should not use these repositories or its packages

More details about the kernel vanilla repos

What kernel versions do the repos currently contain?

Look at this file or cut'n'paste these lines if you want to query the latest status yourself:

releases="26 25 24"; branches="mainline mainline-wo-mergew stable fedora"; \
for branch in ${branches} ; do for release in ${releases} ; do
  queryresult=$(dnf repoquery --repofrompath=repo,http://repos.fedorapeople.org/repos/thl/kernel-vanilla-${branch}/fedora-${release}/x86_64/ --disablerepo=* --enablerepo=repo --available --latest-limit=1 -q kernel 2>/dev/null)
  echo "${branch} ${release} ${queryresult:-not_available}" 
done; done | column -t | sed 's!kernel-0:!!; s!.x86_64!!;'

Who is behind this effort?

Right now the kernel vanilla repositories for Fedora are maintained by Thorsten Leemhuis (aka "knurd") only. Maybe over time people join to help, that's why this text is written as if a team is keeping care of the repositories.

How can I uninstall all kernels from the kernel vanilla repositories

Boot into a stock Fedora kernel and run

sudo dnf remove $(rpm -qa 'kernel*' | grep '.vanilla.knurd' )

DNF will then show what is about to get uninstalled; review that list carefully and make sure you still have a none vanilla kernel on your system, otherwise you loose the ability to boot your installation. Better abort if something looks fishy.

What is the goal of these repositories? Are these kernels as good as those Fedora provides?

These and many other questions are answered in the FAQ about the kernel vanilla repositories.

Known issues and differences

The following sections will list differences to Fedora's proper kernel packages that might be relevant to users. It will also list known problems specific to the packaging of the vanilla kernels.

General

iio-tools are disabled due to a build problem

ToDo list

enable some of the staging drivers Fedora avoids (basically those a well known add-on repository for Fedora ships as add-on package)
automate builds more to keep repos more up2date
automate builds for stable-testing kernels
