The dependencies of Qt are fine, you just ended up in an unfortunate situation that makes it look as if the dependencies in Qt are wrong. The upgrade from Qt 6.4 to 6.6 involves a number of Break+Replaces, but that doesn't mean anything is wrong. In your first example, you only wanted to upgrade libqt6core6t64. The thing here is that there are multiple solutions about what to do with the reverse dependencies. Some solutions remove a lot of them and install as little as possible, others replace a bunch of libs and remove fewer packages. You asked apt to upgrade libqt6core6t64 and that is exactly what apt did. The issue is that the proposed solution is correct, but it's just not your preferred one. In your second example, removing all those libraries without replacing them is not a viable option, because that would make wireshark uninstallable. Therefore, apt installs a number of libs to satisfy the dependencies of wireshark. So in both cases, apt proposes a solution that does exactly what you asked it for. In the first example, there are multiple solutions and apt happened to pick one that you don't want. Why it picked that one and not another one, I do not know. Maybe it found this solution quicker. But all that doesn't mean that the dependencies in Qt are wrong. In fact, all the libs that apt wants to remove are not compatible with libqt6core6t64 6.6.2 and therefore removing them is correct. I absolutely do not see that this is a problem with Qt's dependencies. It's just that apt gives you a correct solution that you don't like and hence have to adjust the upgrade command slightly. But nothing is wrong with Qt's dependencies. You can either close this bug or you can re-assign the bug to apt and turn it into a wishlist item suggesting that apt give you more than 1 solution in such cases. -- Med vänliga hälsningar Patrick Franz
