ubuntu – 为什么apt-get install要求更新nginx.conf？如何使用

我试图使用chef脚本安装几个与nginx无关的软件包(例如htop).但它失败了,因为它要求更新nginx.conf和nginx / sites-available / default.我可以选择使用厨师. (我也不想覆盖,因为我想了解并修复问题而不是逃避它)

因此我尝试通过运行命令sudo apt-get install htop自行安装htop,并得到以下输出.

ubuntu@ip-10-150-4-249:~? sudo apt-get install htop

   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.

然后我尝试安装已安装的cmake sudo apt-get install vim,我仍然遇到同样的错误.输出如下
