[Bug]: Installation fails due to missing Git submodule https://github.com/Stability-AI/stablediffusion.git

Checklist

• The issue exists after disabling all extensions
• The issue exists on a clean installation of webui
• The issue is caused by an extension, but I believe it is caused by a bug in the webui
• The issue exists in the current version of the webui
• The issue has not been reported before recently
• The issue has been reported before but has not been fixed yet

What happened?

Installation fails immediately because the launcher tries to clone a GitHub repository that no longer exists (https://github.com/Stability-AI/stablediffusion.git). This causes a fatal Git error and prevents the WebUI from starting, even with a correct Python setup or when using the release ZIP. This blocks new users from installing the software.

Steps to reproduce the problem

Download the latest official release ZIP of stable-diffusion-webui from the AUTOMATIC1111 GitHub.
Extract the ZIP on Windows.
Run webui-user.bat.
During startup, the launcher attempts to clone https://github.com/Stability-AI/stablediffusion.git.
The repository does not exist, causing a Git error (Error 128).
The WebUI stops and does not launch.

What should have happened?

The WebUI should launch successfully without Git errors, complete setup automatically, and open the user interface in the browser.

What browsers do you use to access the UI ?

Mozilla Firefox

Sysinfo

Sysinfo unavailable:
WebUI cannot be started due to a fatal Git clone error during initial launch (Stability-AI/stablediffusion.git repository not found). The installation folder was removed after repeated failed attempts, so a sysinfo file could not be generated.

Console logs

Console logs unavailable:
The WebUI fails during initial startup before the interface or logging system initializes. The process stops with a fatal Git error while attempting to clone https://github.com/Stability-AI/stablediffusion.git (repository not found). Because the UI never successfully starts and the installation folder was removed after repeated failures, full console logs cannot be provided.

Additional information

This issue occurs on a clean setup following the official installation instructions, with no local modifications. The failure happens consistently on first launch and appears to be caused by a hard-coded reference to a deleted GitHub repository, not by environment configuration.

#17213

This worked for me.

It appears that all new fixes go to the dev branch now, not master.

Thanks for the clarification.
This confirms the issue: the default install still targets master, which is currently broken, while fixes only exist on dev.
This causes fresh installs to fail before the UI can start. Either master needs to be fixed, or the installer/docs should explicitly default to dev to prevent broken first-time installs.

it's 404 too - https://github.com/wew/stablediffusion

You've provided excellent documentation of this issue. This is indeed the same Stability-AI repository problem affecting many users today.

The repository https://github.com/Stability-AI/stablediffusion.git has been taken down (404), breaking all new installations.

Since you mentioned this affects even the official release ZIP, the issue is in the hardcoded repository URL in the codebase. The maintainers need to update this to point to an alternative repository.

For now, there's no clean workaround for new installations. Keep watching the repo for an official fix - this is a critical blocker affecting everyone trying to install.

@nellappli-nell You can try add on webui.bat, it works for me

set STABLE_DIFFUSION_REPO=https://github.com/joypaul162/Stability-AI-stablediffusion.git
set STABLE_DIFFUSION_COMMIT_HASH=f16630a927e00098b524d687640719e4eb469b76

I updated sd.webui.zip so the fix is included by default
uses who use that package (assuming that package works for them) don't need to add the add

set STABLE_DIFFUSION_REPO=https://github.com/w-e-w/stablediffusion.git

if they launch using run.bat

---

for people manually cloning and installing the master branch there's nothing much we can do
AUTOMATIC1111 is the only one with the privileges to update the master branch and he's gone silent
me and one other collaborator only have access to the dev branch, and we have fixed dev branch
I have pinned a guide on how to fix ths issue, but people don't read it

There no way to install ? always have a error and open a window of login git hub,
