No, it didn't stop working recently, it never worked – you just didn't
notice until now. The reason is simply that you are not telling apt to
not use the partial directory, so it does use it… and that hasn't changed
recently (or at all). Have you added preference files recently maybe?
(which is another file/directory you are not overriding)
"apt-config dump" gives you a head start on config knobs to tweak, which
also mentions the one responsible for the sources.list fragments directory:
Dir::Etc::sourceparts.
Apart from what Paul said so that you can actually use an entirely
different config, you have properly better luck with setting Dir
and creating some directories inside it instead of trying to override
every subdirectory with Dir::whatever (while apt supports autocreation
of directories it is using, it doesn't do it if "too much" is missing:
e.g. /var/cache/ isn't created, but apt/archives/partial is).
Oh, and while at it stop using AllowUnauthenticated please.
You can look at test/integration/framework in the apt sources for another
example of how apt and dpkg can be instructed to work inside a temporary
directory (Note that e.g. dpkg does some checks based on the installed
version it can find for itself in the status file, which in turn will
influence the behavior of apt. MultiArch support is a prime example, so
depending on what you are doing, /dev/null might not be enough…).
