我刚刚安装了 Linux Mint 19“Tara”（Ubuntu Bionic 衍生品），Krusader 无法像 18.2“Sonya”（Ubuntu Xenial 衍生品）那样工作。复制/移动的进度条未显示，我在终端中看到以下错误消息：

当我开始复制时，Couldn't start kuiserver from org.kde.kuiserver.service: QDBusError("org.freedesktop.DBus.Error.ServiceUnknown", "The name org.kde.kuiserver was not provided by any .service files")会出现下面的另外两条消息。
有什么想法如何修复它吗？

我建议您检查当前安装的软件包并确保安装了 kde-runtime Linux 软件包（apt list kde-runtime）。该软件包应包含 KDE kuiserver 服务 (/usr/bin/kuiserver)。该软件包将安装 /usr/bin/kuiserver 文件并在 /usr/share/dbus-1/services 目录中创建一个名为 org.kde.kuiserver.service {;^)> 的服务文件
