使用-y运行apt-get（或aptitude）但不提示更换配置文件？
在Ubuntu 10.04上运行apt-get -y install ，我想apt-get （或aptitude如果这样更容易）在安装其他依赖项时不提示我（ -y行为，据我了解）并且没有提示我覆盖配置文件，而是假设始终保留现有的（通常是默认值）。 不幸的是--trivial-only根据man页， --trivial-only似乎是-y的反转并且不会影响显示的提示。
特别是作为samba ， nullmailer ， localepurge和lighttpd包auch强迫我与终端进行交互，即使整个过程是脚本化的并且意味着非交互式。
你可以使用：
sudo apt-get update sudo apt-get -o Dpkg::Options::="--force-confdef" -o Dpkg::Options::="--force-confold" dist-upgrade
仅适用于特定包，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"; }
