I'm running ComfyUI on Arch Linux with a 4090.

Here is the exact procedure I used to install ComfyUI

Install ComfyUI + ComfyUI Manager

git clone [email protected]:comfyanonymous/ComfyUI.git
cd ComfyUI/custom_nodes
git clone [email protected]:Comfy-Org/ComfyUI-Manager.git comfyui-manager
cd ..
uv python pin cpython-3.12
uv venv
uv pip install --pre torch torchvision torchaudio --index-url https://download.pytorch.org/whl/nightly/cu128
uv pip install --pre triton sageattention
uv pip install -r requirements.txt
uv pip install -r custom_nodes/comfyui-manager/requirements.txt
uv pip install pip # ComfyUI-Manager complains if I don't install this

Running

uv run main.py --use-sage-attention

Everything looks and runs perfectly normal. The problem is that ComfyUI-Manager doesn't see itself as installed (please see screenshot) despite it being installed and me using it just fine within ComfyUI.

Furthermore certain plugins like Crystools, ComfyUI-GGUF, and WanVideoWrapper, I can install and use them just fine, but they also don't show up in the ComfyUI-Manager list as being installed and it fails when I try to update them as well. Doesn't matter if I restart, completely kill and reopen ComfyUI, etc.(Most other custom nodes I've installed do work fine though and show up in the Installed list).

This happened recently on my existing installation of ComfyUI with ComfyUI-Manager and also has reappeared on 4 or 5 fresh installations as well.

Any help is greatly appreciated
