我正在尝试安装 fcitx5-frontend-qt5 包，以便在 qt 应用程序上使用它。不幸的是，每次都会出现这个错误：

The following information may help to resolve the situation:
The following packages have unmet dependencies:

正如错误消息所示，它缺少依赖项 qtbase-abi-5-12-8。据我所知，该软件包是 libqt5core5a 的一部分，我已经安装了它。该消息还说我保留了损坏的软件包，但 apt-mark unhold libqt5core5a 显示该软件包没有被保留。
如果有人知道是什么导致了这个问题，请告诉我。谢谢。
