我有一个用于从 deb 文件更新的系统更新脚本：
find /packages/apt/ -type f -name "*.deb" -exec dpkg --force-depends -i {} \+
问题是 nginx 的配置文件被更改了——因此提示：
Configuration file '/etc/logrotate.d/nginx'
==> Modified (by you or by a script) since installation.
==> Package distributor has shipped an updated version.
What would you like to do about it ? Your options are:
Y or I : install the package maintainer's version
N or O : keep your currently-installed version
D : show the differences between the versions
Z : start a shell to examine the situation
The default action is to keep your current version.
*** nginx (Y/I/N/O/D/Z) [default=N]
并且（我认为，没有明确证明）它最终会超时并失败
我在标准输出中看到：
Setting up nginx (1.10.2-1~trusty) ...
Configuration file '/etc/logrotate.d/nginx'
==> Modified (by you or by a script) since installation.
==> Package distributor has shipped an updated version.

*** nginx (Y/I/N/O/D/Z) [default=N] ? dpkg: error processing package nginx (--install):
EOF on stdin at conffile prompt
我怎样才能做一些与之比较的事情：
apt-get install -y --force-yes？（在文档中没有找到任何内容）
答案1
好吧 - 最后很简单 - 只需在前面打一个“是”即可：
yes | find /packages/apt/ -type f -name "*.deb" -exec dpkg --force-depends -i {} \+
