Error message

failed to resolve latest stable release from {url}

What it means

fetch_latest_stable_tag_from_redirect_url follows the stable-release redirect to discover the latest tag. After exhausting UPDATE_HTTP_ATTEMPTS without a captured error, it throws this error naming the redirect URL. It means the latest stable release could not be resolved.

Solutions

1. Retry after checking the release host's status (https://www.githubstatus.com).
2. Authenticate with a token to raise API rate limits if 403 rate-limit responses were seen.
3. Bypass a misbehaving proxy or configure HTTPS_PROXY correctly.
4. Pin/verify the version manually if automated resolution remains unavailable.

// check the redirect resolves before parsing
const res = await fetch(latestUrl, { redirect: 'follow' });
if (!res.ok) console.error('cannot resolve latest release:', res.status);

match fetch_latest_stable_tag_from_redirect_url(client, url) {
  Err(e) if e.to_string().contains("failed to resolve latest stable release") => {
    // fall back to a pinned known-good version
  }
  other => other,
}

When it happens

Trigger: All attempts to resolve the redirect (e.g. /releases/latest) failed with retryable statuses and no last_error was captured, or the loop exited without success.

Common situations: GitHub outage or rate limiting during `codewhale update`; a network path that never serves the redirect endpoint; DNS or captive portal returning retryable gateway errors.
