在 Debian 8.4 上将 Nginx 服务器更新到 1.10

Question

我刚刚在虚拟机上安装了最新的 Debian 版本 (8.4)，一切正常。

然后我从 Debian repos 安装了 nginx 服务器，我得到了 1.6.2 版，而可用的最新版本是 1.10，所以我想更新它。

我尝试这样做的方式可能是错误的，但这就是我迄今为止所发现的。

我首先通过以sources.list这种方式将 nginx 存储库添加到文件中来更新我的存储库：

sudo sh -c "echo 'deb http://nginx.org/packages/debian/ `lsb_release -cs` nginx' >> /etc/apt/sources.list"
sudo sh -c "echo 'deb-src http://nginx.org/packages/debian/ `lsb_release -cs` nginx' >> /etc/apt/sources.list"
curl http://nginx.org/keys/nginx_signing.key | apt-key add -
sudo apt-get update

然后，我尝试使用以下命令安装最新的 nginx 版本：

sudo apt-get install nginx

我得到这个问题：

我该如何解决这个问题？

Answer 1

基本错误是这样的（强调我的）：

dpkg: error processing archive /var/cache/apt/archives/nginx_1.10.0-1~jessie_i386.deb (--unpack):试图覆盖'/etc/default/nginx'，它也在 nginx-common 1.6 包中.2-5+deb8u1

这意味着您正在安装的新软件包试图覆盖另一个软件包（您安装的nginx-common）提供的文件，并且dpkg担心会破坏东西并拒绝这样做。

简单的解决方案是完全删除nginx-common软件包，然后再次安装新版本：

sudo apt-get purge nginx-common
sudo apt-get install nginx
