我确信这是一个已知问题，但我找不到准确的答案。抱歉，如果是这种情况。
我正在尝试dnf system-upgrade从完全更新的 Fedora 23 升级到 Fedora 26（或 25、或 24）。当我尝试时
dnf system-upgrade download --refresh --releasever=26 --allowerasing
dnf 告诉我：
Install 179 Packages
Upgrade 1614 Packages
Remove 4 Packages
Skip 746 Packages
746 个跳过的软件包中，除了 10 个之外，所有软件包都来自fedora存储库本身，而不是来自第三方。另外 10 个来自rpmfusion-free.有些被跳过的包并不重要，但有些却至关重要，比如 anaconda 本身！这本质上与我尝试过的发行版本无关：24、25 或 26。
显然，这次升级将导致系统更新一半并且可能非常不稳定。
为什么有这么多跳过的包，我该如何解决这个问题？怎么样一个dnf distro-sync --allowerasing 事先的升级？
以下是跳过的包的列表。
谢谢！
