debian和apache2安装

Question

我刚刚登录到我新购买的VPS服务器，它使用debian并尝试安装apache2，下面是作为根用户发生的事情：

vs12-101:/# apt-get install apache2
Reading package lists... Done
Building dependency tree... Done
apache2 is already the newest version.
0 upgraded, 0 newly installed, 0 to remove and 13 not upgraded.

在它永远像现在这样之后，请帮我解决这个问题。

关键可能是：

/usr/sbin/make-ssl-cert: line 74: mktemp: command not found
dpkg: error processing ssl-cert (--configure):
subprocess post-installation script returned error exit status 1

这意味着由于缺少命令mktemp，ssl的配置失败。若要修复，请尝试安装包mktemp。那就去做

dpkg --configure --pending

若要完成所有未配置包的配置，请执行以下操作。

即使如此，这还是很奇怪。mktemp在Debian中被标记为“必不可少”，这意味着应该始终安装它。你用了什么强制的选择吗？你的系统好像出问题了。
