check_update get version failed. e:%r

Error message

check_update get version failed. e:%r

What it means

check_update wraps update_from_github.get_github_versions() in try/except; any exception while fetching release info from GitHub (network error, DNS, non-200/JSON-decode failure) is logged and the update check silently returns.

Solutions

  1. Verify connectivity to api.github.com / github.com from the machine (curl -I https://github.com)
  2. Configure a working proxy for the launcher (often required where GitHub is blocked) and retry check update
  3. If behind rate limits, wait and retry later
  4. Update the launcher, since manifest/API format changes are fixed in newer versions
Defensive patterns

Strategy: try-catch

Validate before calling

def github_reachable(timeout=10):
    import urllib.request
    try:
        urllib.request.urlopen('https://github.com', timeout=timeout)
        return True
    except Exception:
        return False

Try / catch

try:
    versions = get_github_versions()
except Exception as e:
    log.warning('check_update failed: %r', e)
    return None  # degrade gracefully, retry next cycle

Prevention

When it happens

Trigger: check_update called from update_check_loop, req_update_handler, or on_check_update when get_github_versions raises — typically an API request to github.com failing or returning unexpected content.

Common situations: GitHub unreachable from the user's region/network; TLS interception; GitHub API rate limiting or schema change breaking parsing; missing network before the proxy is up.
