HAProxy with Debian/squeeze clients causing random “Hash Sum mismatch”

Thursday, July 2nd, 2015

Update on 2015-07-02 22:15 UTC: as Petter Reinholdtsen noted in the comments: Try adding /etc/apt/apt.conf.d/90squid with content like this: Acquire::http::Pipeline-Depth 0; It turn off the feature in apt confusing proxies. ” – this indeed avoids those “Hash Sum mismatch” failures with HAProxy as well.
