错误内容：安装virtualbox 和 genymotion 时，打开genymotion 报错：“ “An error has occurred while trying to create a virtualbox host-only network interface””
环境：virtualbox6.1 genymotion3.1 ubuntu20.04
首先尝试 输入
sudo /usr/lib/virtualbox/vboxdrv.sh status //查看当前virtualbox状态
如果返回“VirtualBox kernel modules (vboxdrv, vboxnetflt, vboxnetadp, vboxpci) are loaded” 则考虑重新安装其他版本的virtualbox
如果没有返回上述语句，尝试输入
sudo modprobe vboxdrv //重新加载内核模块
如果加载失败，尝试
sudo /sbin/vboxconfig
如果依然错误，尝试
sudo apt-get --reinstall install virtualbox-dkms
博主尝试最后一条语句成功加载virtualbox
