jessie-backports sometimes gives hash sum mismatch

[guangie88]

Depending on the internet connection, sometimes fetching from jessie-backports can give hashsum mismatch (logs at the end). Guide suggests that this could be due to ISP caching: https://www.reddit.com/r/debian/comments/64xk33/jessiebackports_is_giving_a_hash_sum_mismatch/.

Can consider using the newer Debian stretch that doesn't require the above additional package, see example: https://github.com/datagovsg/airflow-pipeline/tree/debian-upgrade.
