Oh, I have the same problem just now…I have found this link:Pulling image fails - failed to unmount temp mount - device or resource busy: unknown · Issue #5538 · containerd/containerd · GitHubSo it might be that image is too big?

@radamesFinally pass that stage, thank you! I have got another problem however…Space stuck in "Building" despite gradio welcome portSpacesI have private Docker-based Space with gradio. The image builds, but the space got stuck in “Building” stage, despite I see in the log: 
Running on local URL:  http://127.0.0.1:7860

To create a public link, set `share=True` in `launch()`.

Which should mean that the app is running, no?LinkDid anyone have similar problems?

Could you try adding the following env variables at the end of you Dockerfile before the CMD ?ENV PYTHONUNBUFFERED=1 \
	GRADIO_ALLOW_FLAGGING=never \
	GRADIO_NUM_PORTS=1 \
	GRADIO_SERVER_NAME=0.0.0.0 \
	SYSTEM=spaces
