我在将 virtualbox-guest-dkms 安装到已安装到 VitualBox(6.1.32) VM 的 Ubuntu 9.04 中时遇到问题。（Guest Additions 和 Extension Pack 也已安装。）我按照网页上的说明进行操作VirtualBox - 如何增加视频内存？为了增加虚拟机使用的图形 RAM 量。
一切都很顺利，直到我尝试按照用户 Johan Vijfhuizen 给出的说明，在虚拟 Ubuntu 的终端内发出以下指令。
sudo apt-get install dkms & sudo apt-get install virtualbox-guest-dkms
这产生了以下结果。
ubuntu@ubuntu-desktop:~$ sudo apt-get install dkms && sudo apt-get install virtualbox-guest-dkms

可以看出，DKMS 已安装在虚拟 Ubuntu 中，但找不到包 virtualbox-guest-dkms。
在虚拟 Ubuntu 中，我编辑了 /etc/apt/sources.list，以便可以找到软件包。软件包 DKMS 已安装到虚拟 Ubuntu 中，这表明列表文件已正确编辑。
我现在如何将 virtualbox-guest-dkms 包安装到虚拟 Ubuntu 中？
[对于那些可能感到疑惑的人，我之所以使用这么老版本的 Ubuntu，是因为这是当年对旧的 2012 OU Sense 微控制器板进行测试的 Ubuntu 版本，而我正试图复制其 IDE 运行的环境。]
