Ubuntu 16.04 命令行 sendmail 安装挂了

Question

我试图安装 sendmail 但它在尝试生成 ssl 证书时挂起。我取消了安装过程，后来杀死了锁定任何新软件包无法安装的进程。

但是每当我运行apt-get install <package_name>它时，它都会返回到 sendmail 安装并尝试安装 ssl 证书。

我已经重新启动系统，但问题仍然存在。

我该如何解决？

可以在这里找到类似的问题，但没有解决方案。OP 刚刚更改了操作系统。

我也刚遇到这个问题。它似乎挂在这个脚本的第 240 行/usr/share/sendmail/update_tls。

为了解决这个问题，我执行了以下命令：

cd /etc/mail/tls
sudo openssl dsaparam -out sendmail-common.prm 2048
sudo chown root:smmsp sendmail-common.prm
sudo chmod 0640 sendmail-common.prm
sudo dpkg --configure -a

它现在应该安装。
