Please debug this further, it's not reproducible from the outside. You'll need to recompile apt with some changes, and run it: 1. Find the Fail() call where it says "Data left in buffer" and replace that call with an abort(), collect a coredump, and give me a full backtrace 2. Remove the message "Data left in buffer" from the call argument list, so it just says Fail(false) or Fail(true), and then see what the error message says. To run a local apt build, after building with debian/rules, use: ./obj-x86_64-linux-gnu/cmdline/apt -oDir::Bin::Methods=$PWD/obj-x86_64-linux-gnu/methods Alternatively, if you can provide SSH access to a machine exhibiting this bug, you may also do so. It needs to have apt build dependencies installed so apt can be built. Note that the bug might disappear if the MTU changes somewhere in your network, your bandwidth changes, the server responds in different chunks, or the affected package gets updated and becomes a different size.
