在我的一台 Ubuntu 19.10 机器上，我从存储库安装的 VBox 非常不稳定——我的机器因神秘错误而冻结，而我在论坛上发帖求助却无人理睬。所以我尝试本地构建 VirtualBox。
成功配置后，apt source我开始构建，kmk但构建失败，并出现此问题主题行中的错误。
我尝试通过为 VBox 安装 x11 库来修复此问题，但遇到了以下问题。
怎么解决这个问题？
kmk all
/hd2/projects/virtualbox-6.0.14-dfsg/src/VBox/Additions/x11/Makefile.kmk:34: /hd2/projects/virtualbox-6.0.14-dfsg/src/VBox/Additions/x11/x11stubs/Makefile.kmk: No such file or directory
kmk: *** No rule to make target '/hd2/projects/virtualbox-6.0.14-dfsg/src/VBox/Additions/x11/x11stubs/Makefile.kmk
apt search for virtualbox x11得到：
virtualbox-guest-x11 - x86 virtualization solution - X11 guest utilities
virtualbox-guest-x11-hwe - x86 virtualization solution - X11 guest utilities
但是，当我尝试安装时，virtualbox-guest-x11-hwe出现全彩色警告弹出窗口：
