我刚刚登录到我新购买的使用 debian 的 VPS 服务器并尝试安装 apache2，以下是以 root 身份发生的情况：
vs12-101:/# apt-get install apache2

apache2 is already the newest version.

关键的一行可能是这样的：
/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，ssl-cert 的配置失败mktemp。要修复，请尝试安装包mktemp。然后执行
dpkg --configure --pending
完成所有未配置包的配置。
即便如此，这还是很奇怪。mktemp 在 Debian 中被标记为“必需”，这意味着它应该始终安装。您是否对 dpkg 或 apt-get 使用了某些 --force 选项？您的系统似乎出了问题。
