The --retry flag by default only retries on transient network errors (connection failures, timeouts) but does NOT retry on HTTP error codes like 502 Bad Gateway. To retry on HTTP errors, you need to add the --retry-all-errors flag. The curl command should be:

curl -fsSL --retry 3 --retry-delay 5 --retry-all-errors -o "${TEMP_DIR}/checksums.txt" "${CHECKSUMS_URL}"

Note: --retry-all-errors was added in curl 7.71.0 (June 2020). If backward compatibility with older curl versions is a concern, you may need to check the curl version first or implement manual retry logic instead.

This issue also appears in the following locations of the same file:

The --retry-delay 5 adds up to ~15s extra time on a fully failing download. This is a reasonable tradeoff for reliability. The flags are consistent across both scripts. ✅
