What's in this directory?

These are files containing live images for the Debian GNU/Linux operating system. They are specifically for the amd64 architecture.

There are multiple different files here, corresponding to the different desktop environments..

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 media, either writeable DVD or a USB stick.

How can I verify my download is correct and exactly what has been created by Debian?

There are files here (SHA1SUMS, SHA256SUMS, etc.) which contain checksums of the images. These checksum files are also signed - see SHA1SUMS.sign, SHA256SUMS.sign, etc. 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.

Non-free Firmware

For convenience for some users, this unofficial alternative build includes non-free firmware for extra support for some awkward hardware.

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 live-wrapper and other software.
