有一天重啟電腦后虛擬機virtual box突然打不開了，提示類似
https://askubuntu.com/questions/900794/virtualbox-rtr3initex-failed-with-rc-1912-rc-1912
參考帖子中查看了一下包的情況dpkg --list virtualbox-* | grep ii
結果：
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
發現是安裝的版本不知何時升級的不一致了，只要升級一下就好了舊版本的包就好了
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，恢復正常
