我尝试安装虚拟盒但出现以下错误。
$ sudo /sbin/vboxconfig
[sudo] password for dude:
vboxdrv.sh: Building VirtualBox kernel modules.
This system is not currently set up to build kernel modules (system extensions).
Running the following commands should set the system up correctly:
apt-get install linux-headers-4.4.0-24-generic
(The last command may fail if your system is not fully updated.)
apt-get install linux-headers-generic
vboxdrv.sh: failed: Look at /var/log/vbox-install.log to find out what went wrong.
This system is not currently set up to build kernel modules (system extensions).
Running the following commands should set the system up correctly:
apt-get install linux-headers-4.4.0-24-generic
(The last command may fail if your system is not fully updated.)
apt-get install linux-headers-generic
There were problems setting up VirtualBox. To re-start the set-up process, run
/sbin/vboxconfig
as root.
我当前的内核是：
$ uname -r
4.4.0-24-generic
尝试升级标题给我以下信息。
$ sudo apt-get upgrade && sudo apt-get install linux-headers-generic

linux-headers-generic is already the newest version (4.4.0.21.22).
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
尝试直接从 deb 安装 linux-headers-4.4.0-24-generic，仍然出现错误。从 apt-get 中我得到：
$ sudo apt-get install linux-headers-4.4.0-24-generic
Reading package lists... Done
Building dependency tree
Reading state information... Done
Package linux-headers-4.4.0-24-generic is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Package 'linux-headers-4.4.0-24-generic' has no installation candidate
肯定有办法解决这个问题。有什么建议吗？帮帮忙！

您提供的输出apt-cache policy linux-headers-4.4.0-24-generic是此问题根本原因的重要线索。由于命令报告（部分），Candidate: none很明显您的系统上未正确设置存储库，因此它不知道在哪里找到所需的包。将其添加http://us.archive.ubuntu.com/ubuntu/ trusty-updates/main到您的源列表中，您应该能够安装该包。
