[Ubuntu 22.04][Agent] openclaw CLI fails to start in sandbox — plugin runtime install errors

[zNeill]

Description

Description
Inside a fresh NemoClaw v0.0.41 sandbox on Ubuntu 22.04, the first openclaw agent (or openclaw tui) invocation exits 1 immediately during CLI bootstrap. The bundled plugin loader fails to install runtime-deps for 50+ provider plugins (alibaba, anthropic, arcee, browser, byteplus, chutes, cloudflare-ai-gateway, comfy, copilot-proxy, deepgram, deepseek, device-pair, document-extract, elevenlabs, fal, github-copilot, groq, huggingface, kilocode, litellm, memory-core, microsoft, microsoft-foundry, minimax, mistral, moonshot, nvidia, opencode, opencode-go, openrouter, phone-control, qianfan, qwen, runway, sglang, stepfun, synthetic, talk-voice, tencent, together, venice, vercel-ai-gateway, vllm, volcengine, voyage, vydra, web-readability, xiaomi, zai), with EXDEV: cross-device link not permitted on rename of each plugin's staging dir to its final extension dir. Blocks all sandbox-side agent / TUI / skill / inference operations. Surfaced as failures of DevTest templates T5882196 and T5882242 on GitLab pipeline 51235361 (job 317855910).

Environment

Device:        GitLab runner kw7pofKjH (ubuntu22)
OS:            Ubuntu 22.04
Architecture:  x86_64
Node.js:       Not captured in trace
npm:           Not captured in trace
Docker:        Docker CE, running (version not captured)
OpenShell CLI: openshell 0.0.39
NemoClaw:      v0.0.41
OpenClaw:      2026.4.24-17c3fa238f70

Steps to Reproduce

1. Fresh Ubuntu 22.04 host (no GPU), Docker CE running, no previous NemoClaw install.

2. curl -fsSL https://www.nvidia.com/nemoclaw.sh | bash    # installs NemoClaw v0.0.41

3. NEMOCLAW_NON_INTERACTIVE=1 NEMOCLAW_PROVIDER=build NEMOCLAW_ACCEPT_THIRD_PARTY_SOFTWARE=1 \

     NVIDIA_API_KEY= nemoclaw onboard --fresh --name smoke

4. nemoclaw smoke connect       # enter sandbox

5. openclaw agent --agent main -m "hello" --session-id smoke

Expected Result

openclaw CLI starts; agent returns a non-empty response; exit code 0.

Actual Result

[openclaw] Failed to start CLI: PluginLoadFailureError: plugin load failed:

  alibaba: failed to install bundled runtime deps:
