--- title: Downloads x-toc-enable: true ... New releases are announced in the [main news section](news/). If you're more interested in libreboot development, go to the [libreboot development page](../git.md), which also includes links to the Git repositories. The page on [/docs/maintain/](docs/maintain/) describes how Libreboot is put together, and how to maintain it. If you wish to build Libreboot from source, [read this page](docs/build/). READ THIS BEFORE UPDATING LIBREBOOT, OR YOU MIGHT BRICK YOUR MACHINE ==================================================================== **On newer Intel platforms that require Intel ME and/or MRC firmware, such as ThinkPad X230 or T440p, and/or HP laptops that require KBC1126 EC firmware, the release ROMs of Libreboot are MISSING certain files, that you must insert yourself. FAILURE to adhere to this warning may result in you bricking your machine (rendering it unbootable), if you were to flash the release ROMs without modifying them in any way. For more information, please read:** **[Insert binary blobs on Sandybridge/Ivybridge/Haswell](docs/install/ivy_has_common.md)** NOTE: This warning does not apply to ROMs that you compiled yourself, using lbmk. It only applies to release ROMs, because ME/MRC/EC firmware is *deleted* in release ROMs. The link above says how to re-add them. When building ROM images yourself, from source, Libreboot's build system automatically handles it. See: [Libreboot build instructions](docs/build/) This isn't required on *all* Libreboot-supported boards, but if in doubt, follow these instructions anyway. If you run `blobutil` on a board that doesn't need blobs, nothing will happen. GPG signing key --------------- **The latest release is Libreboot 20230625, under the `stable` directory.** ### NEW KEY Full key fingerprint: `98CC DDF8 E560 47F4 75C0 44BD D0C6 2464 FA8B 4856` This key is for Libreboot releases *after* the 20160907 release. Download the key here: [lbkey.asc](lbkey.asc) Libreboot releases are signed using GPG. ### OLD KEY: This key is for Libreboot 20160907, and releases older than 20160907: Full key fingerprint: CDC9 CAE3 2CB4 B7FC 84FD C804 969A 9795 05E8 C5B2 The GPG key can also be downloaded with this exported dump of the pubkey: [lbkeyold.asc](lbkeyold.asc). sha512sum -c sha512sum.txt gpg --verify sha512sum.txt.sig 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](git.md) HTTPS mirrors {#https} ------------- **The latest release is Libreboot 20230625, under the `stable` directory.** These mirrors are recommended, since they use TLS (https://) encryption. You can download Libreboot from these mirrors: * (University of Kent, UK) * (MIT university, USA) * (Princeton university, USA) * (shapovalov.tech, Ukraine) * (koddos.net, Netherlands) * (koddos.net, Hong Kong) * (cyberbits.eu, France) * (mangohost.net, Moldova) RSYNC mirrors {#rsync} ------------- The following rsync mirrors are available publicly: * (University of Kent, UK) * (Princeton university, USA) * (shapovalov.tech, Ukraine) * (linux.ro, Romania) * (koddos.net, Netherlands) * (koddos.net, Hong Kong) * (mangohost.net, Moldova) 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. How to create your own rsync mirror: 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/ You might put this in an hourly crontab. For example: crontab -e Then in crontab, add this line and save/exit (hourly crontab): 0 * * * * 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.** **NOTE: `rsync.libreboot.org` is not directly accessible by the public, except those whose IPs are whitelisted. For bandwidth reasons, the firewall running on libreboot.org blocks incoming rsync requests, except by specific IPs.** **If you wish to run an rsync mirror, sync from one of the third party mirrors above and set up your mirror. You can then contact Leah Rowe, to have your IP addresses whitelisted for rsync usage - if the IP addresses match DNS A/AAAA records for your rsync host, this can be used. A script runs in an hourly crontab on libreboot.org, that fetches the A/AAAA records of whitelisted rsync mirrors, automatically adding rules permitting them to get through the firewall.** 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: HTTP mirrors {#http} ------------ **The latest release is Libreboot 20230625, under the `stable` 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. * (linux.ro, Romania) * (in-berlin.de, Germany) FTP mirrors {#ftp} ----------- **The latest release is Libreboot 20230625, under the `stable` directory.** WARNING: FTP is also unencrypted, like HTTP. The same risks are present. * (University of Kent, UK) * (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 Linux distros. To comply with GPL v2, 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`.
