Issue installing Stable Diffusion

Support AUR

I am trying to install Stable Diffusion with:

yay -S stable-diffusion-webui

But I am getting:

Anyone successful in installing Stable Diffusion?

The package probably has an issue, as there is a comment submitted last month on its AUR page:

Package is quite broken at the moment.

Perhaps another, more up-to-date, AUR package might work (and also have the benefit of not requiring the compiling of python311 to install). Here’s a list with the most recently updated ones at the top.

Most importantly the repo no longer exist - so there is that - secondly, if it requires Python 3.11 then you should be very careful on Manjaro.

Manjaro provides Python 3.13 on stable and testing branch.

Upstream Arch Linux and Manjaro unstable runs Python 3.14

Github search for stablediffusion repository

I have been playing with AI and various methods to interface to it.

Even the software is not opensource - I find LM Studio to be the most stable and one that doesn’t require endless tweaking et.al.

It is delivered as an appImage - on updates you download a new appImage.

Yes but it was quite some time ago, so I may be out-of-date.

I didn’t use the AUR, and I found the one you tried to install the easiest UI to install at the time (well it was the first one I managed to install, perhaps forge is slightly easier). However it doesn’t seem to have been maintained in the last 2 years.

There’s also forge, not sure which version(s) of python it should work with.

And comfyui, which I never quite got used to. Apparently it works with python 3.13 and even 3.14 though there may be issues with the latter.

There’s another interesting UI, InvokeAI but I couldn’t get it to work at the time. It requires either 3.11 or 3.12, so use the latter.

civitai and huggingface for models, etc.
