使用 -y 运行 apt-get（或 aptitude）但不提示替换配置文件？

Question

apt-get -y install <packages ...>在 Ubuntu 10.04 上运行时，我希望apt-get（或者aptitude如果这样更容易）在安装其他依赖项时不提示我（-y我理解的行为），但不提示我覆盖配置文件，而是假设始终保留现有的（这通常是默认值）。不幸的是，根据页面，它--trivial-only似乎与-y显示的提示相反，不会影响显示的提示man。

在特定的软件包奥赫为samba，nullmailer，localepurge并lighttpd强迫我与终端交互，即使整个过程，脚本和意思是是非交互式的。

您可以使用：

sudo apt-get update
sudo apt-get -o Dpkg::Options::="--force-confdef" -o Dpkg::Options::="--force-confold" dist-upgrade

仅针对特定的包，例如 mypackage1 mypackage2：

sudo apt-get update
sudo apt-get -o Dpkg::Options::="--force-confdef" -o Dpkg::Options::="--force-confold" install mypackage1 mypackage2

Avoiding the conffile prompt

Every time that dpkg must install a new conffile that you have modified
(and a removed file is only a particular case of a modified file in dpkg’s eyes),
it will stop the upgrade and wait your answer. This can be particularly annoying for
major upgrades. That’s why you can give predefined answers to dpkg with the help
of multiple --force-conf* options:

    --force-confold: do not modify the current configuration file, the new version
is installed with a .dpkg-dist suffix. With this option alone, even configuration
files that you have not modified are left untouched. You need to combine it with
--force-confdef to let dpkg overwrite configuration files that you have not modified.
    --force-confnew: always install the new version of the configuration file, the
current version is kept in a file with the .dpkg-old suffix.
    --force-confdef: ask dpkg to decide alone when it can and prompt otherwise. This
is the default behavior of dpkg and this option is mainly useful in combination with
--force-confold.
    --force-confmiss: ask dpkg to install the configuration file if it’s currently
missing (for example because you have removed the file by mistake).

If you use Apt, you can pass options to dpkg with a command-line like this:

$ apt-get -o Dpkg::Options::="--force-confdef" -o Dpkg::Options::="--force-confold" dist-upgrade

You can also make those options permanent by creating /etc/apt/apt.conf.d/local:

Dpkg::Options {
   "--force-confdef";
   "--force-confold";
}

您可以在http://manpages.ubuntu.com/manpages/xenial/en/man1/dpkg.1.html的 dpkg 手册中找到更多信息和更多选项，或者man dpkg查找“confdef”。
