Ok @superboki @FoxxMD @Holaf I have found a serious issue with this container. So the problem is thill the error above. I came across the same issue with comfyui, when i try to install nodes or extension using comfyui-manager. What i found out so far is, that there is a git-https command, that is used everytime you use a "git clone https://xyz" command, which is basically everytime you want to use comfyui-manager or in the example above in stable diffusion the model downloader for certain things.
I have checked and on the docker itself, git is correctly installed with git-https, though, and this is interesting now: git-https is missing in the conda enviroment. The executables for comfyui for example are located under "/config/05-comfy-ui/env/bin".
This is all that is installed regarding git in the conda environment (git-lfs btw is also recommended, had to install that manually using "conda install -c conda-forge git-lfs -y").
So obviously git cant use https for git clone commands, therefore comfyui-manager cant install anything, i constantly get error messages.
I have also checked all the channels that i could find, if any of them has git with git-https as a package available for installing through conda install. Though none have it. So we have an issue here. I am not really familiar with conda and all the environment stuff, so i have no further idea, i am just trial and error atm to find a solution.
Maybe someone of you has a solution in their mind, but this is what i found. Imo this is a serious issue, so this should get fixed asap
