I have a machine where apt-get update hangs for ever with a Waiting for headers message, suggesting that one source is not responding. From this question I know I can do sudo apt-get -o Debug::Acquire::http=true update to identify the culprit. However, it is still complicated to find out which query is not responding, because apt-get seems to be making multiple queries in parallel.How can I can tell apt-get update to only download one file at a time?
