You've constructed an upgrade where the order happens to not expose the bug at hand. In more complex upgrades, apt may order things differently and thus expose the bug in a complex scenario. > Or do you suggest this manual install should be supported? Yes, I do, because it can legitimately be chosen by apt in an upgrade scenario although it usually is not. I also note that fixing this is a rather simple matter of changing d/control, which is why I don't see much benefit in not fixing it. Helmut
