zip: %w

Error message

zip: %w

What it means

Raised when extractFromZip cannot open the downloaded update archive as a valid ZIP file — corrupt download, truncated file, or wrong archive format. It wraps zip.OpenReader's error and aborts the self-update before the cc-connect binary is extracted.
