Package: live-build Version: 1:20191221 744141c60f55144b4d8944ba0d745adcc4b34116 (from MR #97) tried to fix the bug of the source stage generating permissions related warnings when downloading source packages.
the original fix submitted in the MR was to set the permissions of the download directory to 777. the reviewer requested that instead ownership be set to _apt:root, which was the version of the commit that then got merged. unfortunately this modified solution does not work. i do not know why this was not caught at the time, whether i did not bother to test since it seemed so obvious that it should work, or whether something went wrong with conducting a fresh test, but re-running the source stage now i see that the problem still exists. i have been playing around with trying to figure out a suitable alternative to properly solve this but not been successful so far. submitting this as a bug report to ensure that a record is made in case i don't find a solution / i end up forgetting about this / someone else can find a solution in the meantime.
