Information about each Libreboot release can be found at /docs/release/

If you're more interested in libreboot development, go to the libreboot development page, which also includes links to the Git repositories. The page on /docs/maintain/ describes how Libreboot is put together, and how to maintain it. If you wish to build Libreboot from source, read this page.

Git repository

Links to regular release archives are listed on this page.

However, for the absolute most bleeding edge up-to-date version of Libreboot, there is a Git repository that you can download from. Go here:

How to download Libreboot from Git

HTTPS mirrors {#https}

{.imgright}

The latest release is Libreboot 20210522, under the testing directory.

These mirrors are recommended, since they use TLS (https://) encryption.

You can download Libreboot from these mirrors:

RSYNC mirrors {#rsync}

{.imgright}

Useful for mirroring Libreboot's entire set of release archives. You can put an rsync command into crontab and pull the files into a directory on your web server.

If you are going to mirror the entire set, it is recommended that you allocate at least 25GiB. Libreboot's rsync is currently about 12GiB, so allocating 25GiB will afford you plenty of space for the future. At minimum, you should ensure that at least 15-20GiB of space is available, for your Libreboot mirror.

It is highly recommended that you use the libreboot.org mirror, if you wish to host an official mirror. Otherwise, if you simply want to create your own local mirror, you should use one of the other mirrors, which sync from libreboot.org.

Before you create the mirror, make a directory on your web server. For example:

mkdir /var/www/html/libreboot/

Now you can run rsync, for instance:

rsync -avz --delete-after rsync://rsync.libreboot.org/mirrormirror/ /var/www/html/libreboot/

It's extremely important to have the final forward slash (/) at the end of each path, in the above rsync command. Otherwise, rsync will behave very strangely.

If you wish to regularly keep your rsync mirror updated, you can add it to a crontab. This page tells you how to use crontab: https://man7.org/linux/man-pages/man5/crontab.5.html

The following rsync mirrors are available:

  • rsync://rsync.libreboot.org/mirrormirror/ (Libreboot project official mirror)
  • rsync://rsync.mirrorservice.org/libreboot.org/release/ (University of Kent, UK)
  • rsync://mirror.math.princeton.edu/pub/libreboot/ (Princeton university, USA)
  • rsync://qorg11.net/mirrors/libreboot/ (qorg11.net, Spain)
  • rsync://ftp.linux.ro/libreboot/ (linux.ro, Romania)
  • rsync://mirror.koddos.net/libreboot/ (koddos.net, Netherlands)
  • rsync://mirror-hk.koddos.net/libreboot/ (koddos.net, Hong Kong)

Are you running a mirror? Contact the libreboot project, and the link will be added to this page!

You can make your rsync mirror available via your web server, and also configure your own mirror to be accessible via rsync. There are many resources online that show you how to set up an rsync server.

HTTP mirrors {#http}

{.imgright}

The latest release is Libreboot 20210522, under the testing directory.

WARNING: these mirrors are non-HTTPS which means that they are unencrypted. Your traffic could be subject to interference by adversaries. Make especially sure to check the GPG signatures, assuming that you have the right key. Of course, you should do this anyway, even if using HTTPS.

FTP mirrors {#ftp}

The latest release is Libreboot 20210522, under the testing directory.

WARNING: FTP is also unencrypted, like HTTP. The same risks are present.

  • ftp://ftp.mirrorservice.org/sites/libreboot.org/release/ (University of Kent, UK)
  • ftp://ftp.linux.ro/libreboot/ (linux.ro, Romania)

Statically linked

Libreboot includes statically linked executables in some releases, built from the available source code. Those executables have certain libraries built into them, so that the executables will work on many GNU+Linux distros.

Libreboot 20160907 was built in Trisquel GNU+Linux, version 7.0 64-bit. Some older Libreboot releases will have been built in Trisquel 6.0.1.

To comply with GNU GPL v2, Trisquel 6 and 7 source ISOs are supplied by the Libreboot project. You can find these source ISOs in the ccsource directory on the rsync mirrors.

Libreboot releases past version 20160907 do not distribute statically linked binaries. Instead, these releases are source-only, besides pre-compiled ROM images for which the regular Libreboot source code archives suffice. These newer releases instead automate the installation of build dependencies, with instructions in the documentation for building various utilities from source.

These executables are utilities such as flashrom.
