[Bug]: RuntimeError: Couldn't clone Stable Diffusion.

[KaityTT]

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?

The "auto-install" can't find the repository for stablediffusion: Cloning into 'D:\Auto\stable-diffusion-webui\repositories\stable-diffusion-stability-ai'...
remote: Repository not found.
fatal: repository 'https://github.com/Stability-AI/stablediffusion.git/' not found

I checked they repository and they not moved. They deleted the repository. Looks like this is dead now?

Steps to reproduce the problem

Just try to install

What should have happened?

Clean install

What browsers do you use to access the UI ?

No response

Having a similar issue. Im having some issues in the same code lines as yours, but some are also different. After install and clicking webui-user.bat It looks like this on the log

Using this as a core reference for my startup. Pushed some useful extensions to my profile if anyone needs them.

Same issue, install on main doesn't work. Can you please fix so main be working?

Got it! The error you’re seeing is explained in the log itself:
remote: Repository not found.
fatal: repository 'https://github.com/Stability-AI/stablediffusion.git/' not found

Your WebUI is trying to clone/fetch the old repository https://github.com/Stability-AI/stablediffusion.git,
which no longer exists. This is a common issue with newer versions of
SD WebUI if the STABLE_DIFFUSION_REPO is set incorrectly.

You mentioned in your webui-user.bat:

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

That’s correct for the w-e-w version. However, your WebUI is still trying to use the old Stability-AI/stablediffusion repo. This usually happens if the variable wasn’t picked up correctly or an old repository already exists.

Step-by-Step Fix

Delete the old repository

Go to:
C:\AI\stable-diffusion-webui\repositories\

• Delete the folder stable-diffusion-stability-ai.
• This prevents WebUI from trying to fetch the old repo.

Make sure the environment variable is correct

In webui-user.bat, it should be:
set STABLE_DIFFUSION_REPO=https://github.com/w-e-w/stablediffusion.git

• Make sure there are no typos or extra spaces.

Restart WebUI

• Run webui.bat again.
• It should now clone/fetch the w-e-w repository.

Optional: test cloning manually

cd C:\AI\stable-diffusion-webui\repositories
git clone https://github.com/w-e-w/stablediffusion.git stable-diffusion-stability-a
