当我尝试在 Ubuntu Jammy(22.04) 中安装“nullmailer”时，它会提示我提供一些必需的输入，例如您的系统的邮件名称：. 有没有什么方法可以避免在安装和配置安装后出现提示？

Configuring nullmailer
----------------------
This is the fully-qualified host name of the computer running nullmailer. It defaults to the literal name 'me'.
Mailname of your system:
This is a colon-separated list of remote servers to which to send each message. Each entry contains a remote host name or address followed by an optional protocol string 'host protocol'.
The protocol name defaults to smtp, and may be followed by command-line arguments for that module.
谢谢。

正如很多帖子中解释的那样，你可以避免提问这样做：
sudo DEBIAN_FRONTEND=noninteractive apt-get -yq install [packagename]
然后，您需要配置软件包。您还可以使用 Ansible 和这些模块来自动执行任务，并以非交互方式应用您的配置并进行安装。
