This repository serves as a quick, straightforward reference for downloading Debian 14 (Forky) installation images from the official weekly builds. All links provided below are sourced directly from the official Debian CD image server.
- Main Index: https://cdimage.debian.org/cdimage/weekly-builds/
- These images belong to the Testing distribution, which will eventually be released as Debian 14 "Forky".
- Images are provided as full ISO files and Jigdo templates. Using Jigdo is highly recommended to reduce server load and speed up downloads for multi-disc sets.

debian-testing-amd64-netinst.iso |

debian-mac-testing-amd64-netinst.iso |

Explanation:
- The netinst image contains only the core installer and a minimal set of command-line utilities. An active internet connection is required during installation to fetch the desktop environment and additional packages.
- The edu variant is tailored for Debian Edu Pure Blend (schools and educational environments).
- The mac variant is designed for older 64-bit Macs, though it may also work on standard
amd64PCs.

Important Notes:
- Only the first DVD is stored as a complete ISO on the server.
- Additional DVDs (
DVD-2,DVD-3, etc.) are not pre-built to save server storage space. To obtain them, you must use the Jigdo tool (templates are provided in the same directory).- The first DVD is designed to fit on a standard 4 GB USB flash drive.
- If you have a fast internet connection, it is often easier to install the base system from the netinst CD and then install additional software directly from the official Debian repositories.
Besides amd64, weekly build images are also available for the following architectures:
arm64armelarmhfloong64mips64elppc64elriscv64s390xsource(source code)
To access them, simply replace amd64 in the base URL with your desired architecture:
https://cdimage.debian.org/cdimage/weekly-builds/[architecture]/
To ensure your downloaded ISO file is intact and has not been corrupted, follow these steps:
- Download the
SHA256SUMSorSHA512SUMSfile from the same directory where your ISO is located. - Compute the hash of your downloaded file and compare it with the value in the checksum file:
sha256sum debian-testing-amd64-netinst.iso
# or
sha512sum debian-testing-amd64-netinst.iso- For extra security, verify the cryptographic signature (
.signfile) to ensure the checksum file itself is authentic and unmodified.
Full verification guide: https://www.debian.org/CD/verify
- The ISO files are complete and ready to use.
- You can burn them to a CD/DVD or, more commonly, write them directly to a USB flash drive using tools like
dd, Rufus, or BalenaEtcher. - Boot from the USB/DVD, and the Debian installer will launch.
Q: Why aren't all DVD images available for direct download?
A: To conserve server bandwidth and storage, only the first disc of each set is pre-built. All subsequent discs can be regenerated locally using the Jigdo tool.
Q: Do I need to download all the DVDs?
A: No. Most users only need the netinst CD or the first DVD. The installer will fetch any missing packages from the internet if needed.
Q: Do these images include non-free firmware?
A: Yes, these weekly testing images already include non-free firmware packages for hardware that requires them (e.g., certain Wi-Fi or GPU drivers).
These are weekly development snapshots of the Debian Testing branch. They are not stable releases and may contain bugs or unresolved issues. For production environments or mission-critical systems, please use the official Debian Stable release.
