Possible misbehaviours: (a) you've got X~Y installed; X is available and should be installed, but won't be (b) you've got X installed; X~Y is available and shouldn't be installed but will be (a) could happen via partial upgrades -- someone points apt at unstable to get an updated gnome set, but doesn't upgrade dpkg, eg. It's fixable if we make sure every .deb that uses a ~ version Depends:/Pre-Depends: on an appropriate version of apt/dpkg though. (b) could happen if you have bother testing and unstable in your sources.list, and haven't updated apt yet. The real misbehaviours are things like: (c) bar Depends: foo (>= 1.0), foo 1.0~pre1 is installed/available (d) bar Conflicts: foo (<< 1.0) though. It seems fairly straightforward for those sort of things to arise, and I'm not sure how you'd make sure you knew all the cases that could make them arise so as to be confident none of them would. We've lived with the existing situation for ages, it's not urgent enough to risk screwing up our dependency handling; so unless someone can come up with a way of making sure there aren't any problems, it'll just have to wait 'til we're sure everyone's upgraded their apt & dpkg.
