Yes, my problem with the packet isn't that it doesn't have data, but that (according to wireshark's parser) the data that really is there is not parsed as such, plus the header for the next packet is not parsed as a header. The "missed" (by the parser) header seems to happen to apt as well, because it starts waiting until it times out for a reply that never comes. In total, there are 10 requests, and if I look at the data there are 10 replies, but one of them is not parsed as such, so it waits for the last one. I'm not familiar enough with http traffic to see why that header is missed. > This traffic > goes to port 80, so I think the problem has nothing to do with apt- > cacher-ng. Indeed, that was not a very clever suggestion. The reason I thought of this (apart from being confused about which data stream this was) is that I tried to simplify the problem by removing all other repositories from my sources.list. That resulted in the bug disappearing. This is why I'm not so sure if this is (only) a bug in apache, because (the locally running) apache shouldn't notice at all if apt also connects to some other repository on a different port on a different host.
