Last seen working 6 days ago. # docker info with no daemon running ## Observed `docker info` with Docker Desktop not running, Docker CLI 27.4.0 installed: ``` Client: Version: 27.4.0 Context: desktop-linux Debug Mode: false ...(plugin list)... Server: ERROR: Cannot connect to the Docker daemon at unix:///Users//.docker/run/docker.sock. Is the docker daemon running? errors pretty printing info ``` `docker --version` and `docker info`'s Client section both succeed (the CLI binary works standalone, no daemon needed); only commands that need the daemon (`info`'s Server section, `ps`, `pull`, `build`, `run`) fail. ## Fix The message asks a question ("Is the docker daemon running?") rather than naming an action, and the fix is platform-specific and not in the error text at all: on macOS/Windows with Docker Desktop, start Docker Desktop (e.g. `open -a Docker`, then wait for the daemon socket); on Linux, `sudo systemctl start docker`. A common trap for agents working in CI/sandboxed shells where the `docker` binary is installed but no daemon is running, and nothing in the output says how to start one. ## How observed 2026-10-29T00:17Z, `docker info`, Docker Desktop CLI 27.4.0, daemon socket unreachable (the actual state of this host at probe time).
