Impossible to start comfyui

[noahfraiture]

Hello,

I have a very weird behavior. First I only installed dreamshaper model and everything was fine, I was able to start it in comfyui or in forge. But then I installed pony v6 xl and as soon as the download end, the program crash. I restart it and see that pony is correctly installed, but when I try to start comfyui, there's no error but this log

    'TkLibrary': root.tk.exprstring('$tk_library')
}))"'

And if I try to run on forge I have an error with certificates

I'm on NixOS and the path was thus very long, I reduced it, but it's a regular path.

I tried to remove Data and test again but by installing pony model at the beginning, and the behavior is the same : crash when downloaded, and impossible to start comfy and impossible to use forge. Additional note in that direction : if I start comfy while pony is still installing, I can't restart it after stabilityMatrix crash at the end of the download of pony

An additional problem is that I often (like every few seconds) have an error popup

Unobserved Task Exception - DBusException
org.freedesktop.DBus.Error.ServiceUnknown: The name is not activatable

Do you know what could be the problem or how to resolve it ?

Edit : I tried another way with docker, this is my dockerfile

FROM ubuntu:20.04
RUN apt-get update && apt-get install -y fuse icu-devtools openssl libfontconfig1 libx11-dev
WORKDIR /app
COPY StabilityMatrix.AppImage /app/StabilityMatrix.AppImage
RUN chmod +x /app/StabilityMatrix.AppImage
ENTRYPOINT ["/app/StabilityMatrix.AppImage"]

And this is my way to start it

docker build -t stability-matrix .
XAUTH=${XAUTHORITY:-$HOME/.Xauthority}
docker run --privileged \
	-e DISPLAY="$DISPLAY" \
	-e WAYLAND_DISPLAY="$WAYLAND_DISPLAY" \
	-e XDG_RUNTIME_DIR=/tmp \
	-v "$PWD"/data:/app/Data \
	-v "$XDG_RUNTIME_DIR"/"$WAYLAND_DISPLAY":/tmp/"$WAYLAND_DISPLAY" \
	-v /tmp/.X11-unix:/tmp/.X11-unix \
	-v "$XAUTH:/app/.Xauthority" \
	stability-matrix

But I get error
