Description

When running the NemoClaw installer with NEMOCLAW_INSTALL_TAG=v0.0.56, the script completes successfully but the installed CLI is still nemoclaw v0.0.55, even though v0.0.56 is published as the latest release.

Environment

Device:       DGX Spark / Ubuntu 24.04 server / MacBook Pro
OS:           Ubuntu 24.04 / macOS / Windows WSL2
Architecture: x86_64 or arm64
Node.js:      v22.22.3
npm:          10.9.8
Docker:       Docker version 29.2.1, build a5c7197
OpenShell CLI: openshell 0.0.44
OpenClaw:     OpenClaw 2026.5.22 (a374c3a)
NemoClaw:     nemoclaw v0.0.55 (after attempted v0.0.56 install)

Steps to Reproduce

1. Ensure any previous NemoClaw installation is removed, or that you are upgrading in place.
2. Run the official installer with the tag pinned:

   NEMOCLAW_INSTALL_TAG=v0.0.56 curl -fsSL https://www.nvidia.com/nemoclaw.sh | bash

3. After the installer completes, open a new shell (if needed) and run:

   nemoclaw --version

4. Optionally, re-run the installer command again to confirm the behavior is consistent.

Expected Result

• After the script finishes, nemoclaw --version reports nemoclaw v0.0.56.
• If the installer cannot resolve or fetch v0.0.56 for any reason, it should fail with a clear non-zero exit code and a descriptive error (for example, "Requested tag v0.0.56 not available") rather than silently installing a different version.

Actual Result

• The installer completes without any obvious error or warning.
• Running nemoclaw --version still reports nemoclaw v0.0.55 instead of v0.0.56.
• There is no message indicating that the requested tag was ignored or that the script fell back to v0.0.55; from the user's perspective, the tag appears to be accepted but is not actually applied.

Logs

• Terminal transcript of the installer run (stdout and stderr), especially any lines that mention the resolved NemoClaw version or install tag.
• Output of nemoclaw --version before and after the install attempt.

Not captured.

Quick reference

• Component keyword: NemoClaw_Install (and optionally NemoClaw_Upgrade if QE wants to track both new installs and upgrades).
• Severity: 3-Functionality — version pinning via NEMOCLAW_INSTALL_TAG does not behave as advertised; users cannot reliably install the requested released version even when the tag exists.
