我的机器正在运行 Xubuntu Xenial。我最近从软件中心安装了 Audacity。它安装并运行良好。然而，在机器的下一次更新中，我遇到了未满足的依赖关系问题。
我无法添加/删除任何东西。我的理解是我需要安装 libqtcore 版本：4:4.8.7+dfsg-5ubuntu2，但 APT 拒绝安装它。然后似乎文件“Trolltech.conf”发生了一些异常，但我不确定是什么。
发生了什么事？我该如何解决？

按照 GTRONICK 所说的去做，但也一定要先清除 audacitysudo apt purge audacity然后sudo apt upgrade再通过命令行重新安装
sudo apt install audacity。
如果问题仍然存在，您可能需要考虑使用 audacity 的替代方案。Audour 和 Ocenaudio 都不错。
