Virtualbox无法启动

这是使用默认gnome桌面的Ubuntu 18.04的全新安装。

当我尝试启动virtualbox时，它不会加载。 当我从终端运行它时，我收到以下错误消息：

VirtualBox：supR3HardenedMainGetTrustedMain：dlopen（“/ usr / lib / virtualbox / VirtualBox.so”，）失败：libQt5Core.so.5：无法打开共享对象文件：没有这样的文件或目录

我跑的时候：

从终端我可以看到安装了libqt5。

经修正的问题，按要求包括产出：

 terminal prompt: ldd /usr/lib/virtualbox/VirtualBox.so | grep not libQt5Core.so.5 => not found libQt5Gui.so.5 => not found libQt5Widgets.so.5 => not found libQt5Gui.so.5 => not found libQt5Core.so.5 => not found libQt5Widgets.so.5 => not found libQt5Gui.so.5 => not found libQt5Core.so.5 => not found libQt5Widgets.so.5 => not found libQt5Gui.so.5 => not found libQt5Core.so.5 => not found 

第二个命令：

 terminal prompt: ldd /usr/lib/x86_64-linux-gnu/libQt5Core.so.5 | grep not ldd: /usr/lib/x86_64-linux-gnu/libQt5Core.so.5: No such file or directory 

Virtualbox是通过软件中心安装的。

 terminal prompt: dpkg -S /usr/bin/virtualbox virtualbox-qt: /usr/bin/virtualbox 

并要求最新产量：

 terminal prompt: ls -l /usr/lib/x86_64-linux-gnu/libQt5Core* ls: cannot access '/usr/lib/x86_64-linux-gnu/libQt5Core*': No such file or directory 

任何想法如何解决？

谢谢
