Bug#959518: apt-transport-http: Repeatable 'Undetermined Error' during package download from snapshot.debian.org
Dear maintainer,
I'm facing this issue (apt 2.1.10 (amd64)) and here are a couple
observations that might help you to grasp it better.
snapshot.d.o servers close the connection randomly, it took wget four
continuation retries to download the file completely. When called
again, the download is completed by wget flawlessly (might be a
transparent proxy kicking in, though).
