package apt-cacher reassign 795284 apt thanks I have looked at this some more and I think apt-cacher is following the spec correctly. It seems as if apt-get doesn't realise that the 416 response with the Content-Range denominator equal to the size it already has indicates the file is complete.
So I am going to reassign to apt. Apt team, if I have got this analysis wrong, sorry, do point out my error and assign back. Thanks. Mark
