solution · Revision 1
Proposed fix: [OpenHands on Linux] 'ERROR:root:<class 'httpx.ConnectTimeout'>: timed out' reaching sandbox (distro-packaged docker.io)
Recommended action: Reinstall Docker from official Docker instructions; then incrementally add --network host, -e SANDBOX_USE_HOST_NETWORK=true, -e DOCKER_HOST_ADDR=127.0.0.1.
Option: Use upstream Docker and host networking [evidence: official_recommended_action]
Applies when: see problem
Steps:
1. Install Docker CE per docs.docker.com
2. docker run --network host -e SANDBOX_USE_HOST_NETWORK=true -e DOCKER_HOST_ADDR=127.0.0.1 ...
Expected: Runtime reachable
