[Bug]: Repository not found: Stability-AI/stablediffusion (public clone fails)

What happened?

When trying to install Stable Diffusion WebUI on Ubuntu 24.04, the installation script fails with the error: "remote: Repository not found. fatal: repository 'https://github.com/Stability-AI/stablediffusion.git/' not found". This happens even when using a GitHub Personal Access Token. The installation cannot proceed because the required repository is not accessible.

Steps to reproduce the problem

Install dependencies:

sudo apt install wget git python3 python3-venv libgl1 libglib2.0-0

Install Python 3.11:

sudo add-apt-repository ppa:deadsnakes/ppa
sudo apt update
sudo apt install python3.11

Create a new directory and download the webui.sh script:

mkdir stable-diffusion
cd stable-diffusion
wget -q https://raw.githubusercontent.com/AUTOMATIC1111/stable-diffusion-webui/master/webui.sh
chmod +x webui.sh

Run the installation script:

./webui.sh

`The script will attempt to clone the repository https://github.com/Stability-AI/stablediffusion.git, but it will fail with the error: "remote: Repository not found. fatal: repository 'https://github.com/Stability-AI/stablediffusion.git/' not found".

What should have happened?

The installation script should have successfully cloned the required Stable Diffusion repository and continued with the setup.

What browsers do you use to access the UI ?

No response

Sysinfo

Unable to generate sysinfo file because WebUI fails to start due to repository not found error. If needed, I can provide system details manually (Ubuntu 24.04, Python 3.11, RTX 5070 Ti).

Same issue here, the repository does not seem to exist on github anymore: https://github.com/Stability-AI/stablediffusion.git Delivers a 404 page not found error

It seems to have been just changed to private or closed since every search engine i try comes up with the repository as the number 1 result

As a temporary solution I changed the url and hash of the repo to a fork that was made quite recently, the file to edit is in the modules folder and the file to edit is launch_utils.py

Exact lines are 349 and 355

stable_diffusion_repo = os.environ.get('STABLE_DIFFUSION_REPO', "https://github.com/Stability-AI/stablediffusion.git") stable_diffusion_commit_hash = os.environ.get('STABLE_DIFFUSION_COMMIT_HASH', "cf1d67a6fd5ea1aa600c4df58e5b47da45f6bdbf")

Change to

stable_diffusion_repo = os.environ.get('STABLE_DIFFUSION_REPO', "https://github.com/Kantyadoram/stable-diffusion-stability-ai.git") stable_diffusion_commit_hash = os.environ.get('STABLE_DIFFUSION_COMMIT_HASH', "7435a5be1050962a936a4ef624b43814ee8824a8")

This is in no way a permanent solution. I don't know the dev behind that repository.

DO THIS AT YOUR OWN RISK !!!!

it's safer replacing it in the ~~webui.sh~~ (correction: there are multiple files for this purpose already, suggested is webui-user.sh) or wrap the sh with another sh file setting the envs

I found a fork that has a commit that matches the last hash from the official repo:

https://github.com/joypaul162/Stability-AI-stablediffusion

Commit hash: f16630a927e00098b524d687640719e4eb469b76

So this one is an exact match for the original, you should be able to change only the URL to https://github.com/joypaul162/Stability-AI-stablediffusion.git and leave the commit hash as it was.

Thanks Nick, that modification in modules/launch_utils.py fixed the issue for me.

Thanks Nick, worked for me too

Thanks, I added the following to webui-user.bat:

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

and ran run.bat again. This fixed the issue for me.

I am alos running Stable Diffusion WebUI (but on Windows 11), and I am facing the same problem with the "stable-diffusion-stability-ai" repository not being found. Hopefully, the official team can make improvements. QAQ

This is from a reddit post from a month ago and could be related to the repositories here and on huggingface going down:

StableITAdmin posted the following message a day after the platform was brought down:

"...it looks like our team has decided to deprecate SD 2.0 and 2.1. We were told this official statement:

'We have officially deprecated Stable Diffusion 2.0 and 2.1. This is part of our effort to clean up and consolidate our model offering and to get ahead of upcoming compliance requirements for the EU AI Act in 2026. These models have been outpaced by newer architectures that offer far stronger performance, safety, and alignment, and continuing to maintain them does not fit our long-term roadmap.

'If you currently rely on SD 2.0 or 2.1 for an active business use case, please reach out and share your workflow and requirements. While these models will no longer be part of our public lineup, we want to make sure that any legitimate business dependencies are surfaced so we can explore the right path forward with you.'

I also just forked if anyone needs a backup option, same commit hash.

File "D:\stable-diffusion-portable-main\venv\lib\site-packages\torch_meta_registrations.py", line 5351, in zeros_like res.fill_(0) torch.AcceleratorError: CUDA error: no kernel image is available for execution on the device Search for cudaErrorNoKernelImageForDevice' in https://docs.nvidia.com/cuda/cuda-runtime-api/group__CUDART__TYPES.html for more information. CUDA kernel errors might be asynchronously reported at some other API call, so the stacktrace below might be incorrect. For debugging consider passing CUDA_LAUNCH_BLOCKING=1 Compile with TORCH_USE_CUDA_DSA` to enable device-side assertions.

It gave me this error, but it ran in the browser. Images aren't generated.

I think SD2 has long been used in both AIGC community and AI research community. I hope even if stabilityai take it down, the community is going to maintain an official repo of SD2 including checkpoints, codes etc. (also I want SD1.4 SD1.5 back)

I have both sd2-1-base and sd1-5-base checkpoints locally , contact me if any need it.

Hello, is it neccessarry to download that Repo if I downloaded my own model from Huggingface? Could I just completely disable cloning it?
