今天，当我启动 Virtualbox VM 并尝试启用第二个屏幕时，我发现启用它的按钮已“变灰”且无法单击。直到昨天它还正常工作。
我做了一些研究，发现了几个线索（即这个) 表明问题可能出在 VM Guest Additions 上。实际上，其他功能（例如主机和客户机操作系统之间的复制粘贴）已被禁用。
因此，我尝试从 VM 顶部菜单 (设备 > 升级客户机添加项) 更新 Virtualbox 客户机添加项，但出现了此弹出错误：
Creating installation directory "/tmp/" on guest failed: VERR_NOT_FOUND.
Result Code:
VBOX_E_IPRT_ERROR (0X80BB0005)
Component:
GuestSessionWrap
Interface:
IGuestSession {234f0627-866d-48c2-91a5-4c9d50f04928}
我已经检查过目录 /tmp/ 是否存在于我的机器上，但我猜测由于某种原因它无法在那里下载新的安装文件。
所以我想通过终端更新 Virtualbox Guest Additions。
我该怎么做？
我尝试过
依照指示本教程，我尝试重新安装客户添加功能
sudo apt update
我在这里收到消息
4 packages can be upgraded. Run 'apt list --upgradable' to see them

所以我跑
apt list --upgradable
并得到
tommaso@tommaso-VirtualBox:~$ apt list --upgradable
Listing... Done
gjs/jammy-updates 1.72.4-0ubuntu0.22.04.1 amd64 [upgradable from: 1.72.2-0ubuntu2]
libgjs0g/jammy-updates 1.72.4-0ubuntu0.22.04.1 amd64 [upgradable from: 1.72.2-0ubuntu2]
transmission-common/jammy-updates,jammy-updates 3.00-2ubuntu2.1 all [upgradable from: 3.00-2ubuntu2]
transmission-gtk/jammy-updates 3.00-2ubuntu2.1 amd64 [upgradable from: 3.00-2ubuntu2]
然后
sudo apt install build-essential linux-headers-$(uname -r) -y
VM 顶部菜单 > Guest Additions CD Image，似乎什么都没有发生，但我猜测这是因为它们已经安装，但尚未更新。
cd /media/<MY_USER>/VBox_GAs_7.0.4/
sudo ./VBoxLinuxAdditions.run
但我明白
Cannot reload kernel modules: one or more modules is still in use
因此我重新启动了我的虚拟机，然后sudo ./VBoxLinuxAdditions.run再次运行，但没有任何变化。
我已经更新了 VirtualBox 应用程序，但是问题并没有得到解决。
答案1
似乎无法正确安装来宾添加程序，原因是
- 未升级的 apt 软件包
- 重复的行
/etc/apt/sources.list
当我尝试从 Virtualbox 顶栏菜单“设备”虚拟插入并安装 gust additions CD 时，这两个问题导致文件无法VBoxLinuxAdditions.run 在 guest additions 的安装目录中生成。这可能是 Virtualbox UI 弹出窗口显示的错误。/dev/cdrom
我已经解决了这些问题
1-升级软件包
apt list --upgradable
然后运行
sudo apt upgrade <PACKAGE>
对于前一个命令返回的路径的每个“第一级目录”，遵循依赖顺序（如果返回错误则跳过一个包，继续下一个，然后返回）。
例如gjs/jammy-updates 1.72.4-0ubuntu0.22.04.1 amd64 [upgradable from: 1.72.2-0ubuntu2]
-->sudo apt upgrade gjs
2 - 删除 /etc/apt/sources.list 中的重复行
sudo vim /etc/apt/sources.list
然后注释掉第 50 行和第 51 行，如下图所示
W: Target CNF (restricted/cnf/Commands-all) is configured multiple times in /etc/apt/sources.list:5 and /etc/apt/sources.list:50
[...]
W: Target Packages (main/binary-amd64/Packages) is configured multiple times in /etc/apt/sources.list:48 and /etc/apt/sources.list:51
3 - 重试安装 Virtualbox Guest Additions
sudo apt update
不再返回警告，那么
sudo apt-get install build-essential linux-headers-$(uname -r)
然后通过 重新启动虚拟机sudo reboot。
然后，从 VirtualBox 顶栏“设备”菜单 -> 单击“插入客户添加 CD”（它似乎没有执行任何操作，但确实如此）
最后
sudo mkdir -p /mnt/cdrom
sudo mount /dev/cdrom /mnt/cdrom
cd /mnt/cdrom
sudo ./VBoxLinuxAdditions.run
当系统询问您是否要安装客户机添加功能（即使它们已经在操作系统上）时，请继续，然后再次通过 重新启动虚拟机sudo reboot。
这次我看到之前禁用的选项又恢复正常工作了。
