由于系统内核更新等原因，增强功能按常规方法可能会报错，本文介绍如何处理增强功能安装报错的问题。

如果你在使用或安装Guest Additions出现如下问题：

• 内核更新后，如使用apt update，apt upgrade更新内核后，造成挂载的文件读写速度慢等问题
• 安装VirtualBox Guest Additions报“VirtualBox Guest Additions: Kernel headers not found for target kernel 5.10.0-20-amd64. Please install them and execute”

解决这些问题需要安装相应版本的内核头文件。你可以使用以下命令安装当前内核版本的头文件：

sudo apt update
sudo apt install linux-headers-$(uname -r)

这个命令会自动安装与当前内核版本对应的头文件。安装完成后，重新运行 VirtualBox 增强功能安装程序即可完成安装。

以下是错误提示：
