What’s in this directory?
These are files containing source code for the Debian operating system.
How do I use these files?
The files here are complete ISO images, ready to use.
Once you have downloaded all the ISO images you want, you will typically need to write them to installation media.
What size and type of media will I need?
The images described here are sized to be written to writeable DVD media at a minimum, but may be written to larger media if needed.
How can I verify my download is correct and exactly what has been created by Debian?
There are files here (SHA512SUMS, etc.) which contain checksums of the images. These checksum files are also signed — see the matching .sign files. Once you’ve downloaded an image, you can check:
- that its checksum matches that expected from the checksum file; and
- that the checksum file has not been tampered with.
For more information about how to do these steps, read the verification guide.
Only the first few images are available! Where are the rest?
We don’t store/serve the full set of ISO images for all architectures, to reduce the amount of space taken up on the mirrors. You can use the jigdo tool to recreate the missing ISO images instead.
Non-free Firmware
This Debian image build only includes Free Software where possible. However, many systems include hardware which depends on non-free firmware to function properly so this build also includes those firmware files for those cases. See the Debian Wiki non-free firmware page for more information.
Other questions?
See the Debian CD FAQ for lots more information about Debian CDs and installation.
The images here were put together by the Debian CD team , using debian-cd and other software.

How to download a Debian package’s source code?
Downloading source code from Debian repositories is as simple as running apt-get source . It will put 3 files in your current directory, .dsc that describes package, .orig.tar.gz that contains unmodified sources, and .diff.gz that contains Debian-specific changes. But if you get error E: Unable to find a source package for , then you might not have the source code repository specified, so go to /etc/apt/sources.list (or some file in /etc/apt/sources.list.d/ that contains your Debian repository), find a string like:
deb ftp://ftp.debian.org/debian wheezy main contrib non-free deb-src ftp://ftp.debian.org/debian wheezy main contrib non-free Update package index files with sudo apt-get update and try again. See also:
A second possibility is to download the source code from upstream directly instead of downloading it from Debian repositories. This has the advantage that if you not only want to read the source code but might like to change something you can directly commit and submit it to upstream (assuming it is not a Debian patch).
You can usually find out the upstream source code repository URL in the file /usr/share/doc/$package_or_program_name/copyright .

The Universal OS
Debian packages, maintains and distributes many projects developed using GitHub. This account was created to facilitate push/pull interactions with the upstream developers of such projects. If you maintain a package whose upstream developers use GitHub, please feel free to join this group and mirror such project here.
This account is not intended to serve as the canonical (specified with Vcs-* fields of debian/control) location for corresponding Debian source packages. Most often such repositories should be made available on the Debian project’s public forge Salsa to guarantee autonomy.
Open a new issue with a signed statement asking to be added to the organization. The signature needs to be made with your PGP key currently in the Debian keyring. All active Debian Developers will be approved.
You might find following tools available from Debian useful for your interaction with GitHub
github-backup backs up everything GitHub knows about a repository, to the repository
Many thanks to the GitHub admins for their prompt action to release the previous (unused) «Debian» account.
This GitHub organization is not an endorsement of GitHub by Debian. Debian does not maintain or distribute the GitHub engine codebase because it is not available under free and open-source license (see Wikipedia for a list of available free and open-source alternatives). Moreover, this GitHub organization is not an official part of the Debian project. It is maintained by individual Debian developers (signed below) with the sole purpose of being useful.
