スタートVirtualBoxは再起動後に保存する二日前に、アップグレードのUbuntu
問題の原因は、エラーレポートから反射されたVirtualBoxが正しく動作しないので、いくつかのカーネルドライバは、コンパイルされていないからによるものです。実際にはUbuntuの上でこの問題に対処するために、難しいことではありません、以下は、この問題を解決するためのいくつかの手順です：
まず、カーネルヘッダファイルとビルドツールをインストールします。
$須藤はapt-getをインストールビルド不可欠モジュールアシスタント
$ sudoは準備ミリアンペア
その後、VirtualBoxのカーネルドライバが順に記載された前回のレポートのエラーでコンパイルされています。
$須藤/ sbinに/ vboxconfig

参考博文：https://www.linuxidc.com/Linux/2017-11/148871.htm 中 对应的Ubuntu版本较老 /etc/init.d/vboxdre setup 命令不存在
直接执行保存提示的命令即可sudo /etc/init.d/vboxdrv setup
再运行Virtualbox就会变得正常了。
