后缀安装错误

Question

我运行mc，并试图在shell：apt-get install curl postfix中安装curl和后缀。后缀出现了一个配置对话框，在按Ctrl(显示/隐藏MC)两次后，我无法再读取配置消息，所以我退出了MC，使用F10。apt-get过程仍然存在，我用sudo kill xxxx杀死了它。现在apt-get不起作用。

我试过apt-get -f install

dpkg: error processing package postfix (--remove):

以及在各种问题(Q1、Q2、Q3)中提出的其他解决方案：apt-get purge postfix、apt-get --reinstall install postfix、dpkg --pending --configure。

一个非常相似的问题(重复？)是后缀错误，但它没有答案。

我怎样才能修好包管理器？我的操作系统是Debian Jessie。

Bahamut的建议在错误代码102中失败：

X@X ~ % LC_ALL=C sudo dpkg --install /var/cache/apt/archives/postfix_2.11.3-1_amd64.deb

Postfix configuration was not changed.  If you need to make changes, edit
/etc/postfix/main.cf (and others) as needed.  To view Postfix configuration
values, see postconf(1).

After modifying main.cf, be sure to run '/etc/init.d/postfix reload'.

手动删除配置文件的工作方式如下：
