Bug#959518: apt-transport-http: Repeatable 'Undetermined Error' during package download from snapshot.debian.org

[James Addison <jay@jp-hosting.net>]

Package: snapshot.debian.org
Followup-For: Bug #959518

Dear Maintainer,

I've reassigned this issue to both 'apt' and 'snapshot.debian.org' since it
seems possible that either an HTTP client edge case and/or a server-side
connection-handling behaviour may be the cause(s).

It also seems possible that the rate-limiting mentioned previously is being
applied by the snapshot.debian.org server; that would be sensible given that
my client has retried download of packages repeatedly.

I'm not certain whether my bug tracker 'reassign' operation notified the
maintainers of the 'snapshot.debian.org' pseudo-package, so this update also
serves to (hopefully) ensure they're included on the thread.

Thanks again,
James
