Package: apt
Version: 0.9.11.1
Severity: normal
Hello,
Lately dist-upgrade exits with an error message if only some dependencies are
not met. Before this, it would produce output similar to apt-get upgrade and
try to dist-upgrade whatever package is not influenced by the cause of it.
Likewise, dist-upgrade --download-only just exits with the same output and
won't download any package.

Please name the version you mean with "before" so that we can show you
that this was never the case…
If APT can't find a valid solution (like currently in the in-progress perl
transition) it will error out just like this. Sometimes its able to workout
a solution in which stuff is held back, but not always.
Heuristics for the win (not).
In that case you can apply your own holds – and you will notice that this
is quiet involved process, even if you have an unbelievable powerful
computation unit available (aka: a brain) and not just a few thousand lines
of code like APT. Making APT work in such situations would probably be nice,
but its unlikely to happen and not very well defined and so not actionable.
There is a wishlist open for having a flag to ignore dependency errors in
download-only mode. Its not implemented so far.
I am therefore closing this bugreport as non-bug and would like to encourage
filling specific issues (if not already done) as such meta bugs are hard to
deal with.
Best regards
David Kalnischkies
