This is a massive pain in the ass: installing easy diffusion!!!! about easydiffusion

[q5sys]

I just did a fresh install on Rocky Linux and didn't have a problem. Try this and see if it works for you.

1. Download the zip file listed in the README file.
2. Open your terminal and go to your home directory cd ~
3. Create a file in your home directory named ed: mkdir ~/ed
4. move the zip to that folder mv ~/Downloads/Easy-Diffusion-Linux.zip ~/ed/Easy-Diffusion-Linux.zip
5. change to the ed directory cd ~/ed and unzip the file unzip *
6. cd into the directory it creates cd easy-diffusion
7. run the start script start.sh (DO NOT RUN sh start.sh)

It says the error quite clearly: the scripts tried to git clone the repository called sd-ui-files but the directory was already there so the command didn't have permission to overwrite the contents of that directory.

Starting over from scratch could solve it if your system is left at a reasonable state. You could try rm -rf sd-ui-files inside the easy-diffusion directory and try again or just remove everything and start from scratch using the steps @q5sys gave you.
