添加一些存储库并安装缺少的依赖项对我有用：

sudo add-apt-repository universe
sudo add-apt-repository multiverse
sudo add-apt-repository "deb http://download.virtualbox.org/virtualbox/debian bionic contrib"
sudo apt-get update
sudo apt-get upgrade
sudo apt-get install libpng16-16 libqt5core5a libqt5printsupport5 libqt5widgets5 libqt5x11extras5
sudo apt-get install virtualbox-6.0
