Package: apt Version: 0.9.7.9+deb7u6 Severity: important Dear Maintainer,
"apt-get update" with a stale partial Packages file displays a cryptic error 404 leading me to assume that the Packages file doesn't exist and the server is broken. This is made worse by it giving the URL of the Packages file (not including .bz2), which of course does give a 404. So the obvious solution is to download the .bz2'ed version, unpack it and put it in lists - but this bypasses some important security checks. The real solution is to delete the old cached packages files, thus allowing the .bz2 fetch to succeed. This is extremely confusing, even to a user with some technical knowledge! Most likely the problem is apt-get is misunderstanding an error message from the web server when doing a partial fetch; this ought to be fixable. If not, it should delete the partial files itself, and if that isn't possible then at least improve the error message! Don't return a URL (.../Packages) that is guaranteed to fail, and thus probably confuse the user into doing something foolish! This is a "usable security" issue IMHO, in that the obvious solution to the cryptic error messages is dangerous, and the bug usually only arises when the user needs to do an update urgently to fix a security problem (presumably known and exploitable). Even with support from the official IRC channel it took quite some time to resolve this; it's not good enough to dump it on the user, and it wasted some security@debian time too with me panicking about security.debian.org apparently being broken.
