What's Wrong?

Environment

  • Claude Code: v2.1.92
  • OS: Linux (Ubuntu, x86-64)

Observed behavior

On every startup, the status bar shows:

_Failed to install Anthropic marketplace · Will retry on next startup_

Root cause (after I investigated)

The official marketplace auto-install attempts to fetch from:

https://downloads.claude.ai/claude-code-releases/plugins/claude-plugins-official

This URL returns HTTP 404 that means the asset does not exist on the CDN.

<pre>
$ curl -I https://downloads.claude.ai/claude-code-releases/plugins/claude-plugins-official
HTTP/2 404
server: UploadServer
</pre>

The git clone fallback also fails. The outer catch returns reason: "unknown", which triggers the warning notification.

General Anthropic connectivity works fine (https://anthropic.com → 302 OK), so this is not a local network issue.

Impact

Cosmetic/non-blocking — Claude Code functions normally. However:

  • this prevents from loading the plugins as the claude marketplace isn't loaded.

  • The error message gives users no actionable information and reason: "unknown" in the notification is misleading; "gcs_unavailable" or "asset_not_found" might be more accurate

What Should Happen?

the Anthropic marketplace should be installed automatically or upon retry.
