有一天重启电脑后虚拟机virtual box突然打不开了，提示类似
https://askubuntu.com/questions/900794/virtualbox-rtr3initex-failed-with-rc-1912-rc-1912
参考帖子中查看了一下包的情况dpkg --list virtualbox-* | grep ii
结果：
ii virtualbox-dkms 5.1.28-dfsg-2 all x86 virtualization solution - kernel module sources for dkms
ii virtualbox-qt 5.2.2-dfsg-2 amd64 x86 virtualization solution - Qt based user interface
发现是安装的版本不知何时升级的不一致了，只要升级一下就好了旧版本的包就好了
apt-get update
apt-get upgrade virtualbox-dkms*
再次查看dpkg --list virtualbox-* | grep ii
ii virtualbox-dkms 5.2.2-dfsg-3 all x86 virtualization solution - kernel module sources for dkms
ii virtualbox-qt 5.2.2-dfsg-3 amd64 x86 virtualization solution - Qt based user interface
版本一致，恢复正常
