文章描述了在尝试安装xinetd时遇到的错误，如debconf:apt-extracttemplatesfailed和dpkg-deb错误，原因是使用的软件源不适用。解决方法是备份并修改/etc/apt/sources.list文件，将内容替换为阿里云的Ubuntutrusty仓库镜像地址，然后更新软件列表以修复安装问题。

最大的原因：软件源不合适

比如安装xinetd之类的安装失败出现debconf: apt-extracttemplates failed: No such file or directory等等报错，找了很久找到一个源是12.04可以用的。

完整报错：

apt-get install xinetd

The following NEW packages will be installed:
xinetd

解决步骤：

1.sudo cp /etc/apt/sources.list /etc/apt/sources.list.bak #备份

2.sudo vim /etc/apt/sources.list #修改

替换内容：

deb http://mirrors.aliyun.com/ubuntu/ trusty main restricted universe multiverse

deb http://mirrors.aliyun.com/ubuntu/ trusty-security main restricted universe multiverse

deb http://mirrors.aliyun.com/ubuntu/ trusty-updates main restricted universe multiverse

deb http://mirrors.aliyun.com/ubuntu/ trusty-proposed main restricted universe multiverse

deb http://mirrors.aliyun.com/ubuntu/ trusty-backports main restricted universe multiverse

deb-src http://mirrors.aliyun.com/ubuntu/ trusty main restricted universe multiverse

deb-src http://mirrors.aliyun.com/ubuntu/ trusty-proposed main restricted universe multiverse

deb-src http://mirrors.aliyun.com/ubuntu/ trusty-backports main restricted universe multiverse

3.保存后更新sudo apt-get update #更新列表
