Fixes #772 The install script was failing with "Checksums do not match" when the GitHub API rate limit was hit or network issues prevented retrieving the latest release version. Changes: - Add validation to check if version is empty before proceeding - Provide helpful error message explaining the issue - Suggest workaround using manual version specification - Remove redundant get_checksum_url call - Add missing ;; in get_machine function for consistency 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
