问题描述
我正在尝试安装sendmail，但尝试生成ssl证书时却挂起。我已经取消了安装过程，后来又取消了锁定所有新软件包的过程。
但是，每当我运行apt-get install <package_name>时，它就会返回到sendmail的安装并尝试安装ssl证书。
我已重新启动系统，但问题仍然存在。
我该如何解决？

最佳思路
我也遇到了这个问题。它似乎挂在此脚本/usr/share/sendmail/update_tls的第240行上。
为了解决该问题，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
现在应该安装。
