我试图升级nginx 1.2.1到版本1.2.6在Ubuntu 12.10，但没有运气。 我以前安装nginx使用apt-get install nginx-full因为我需要模块而不是从源代码构build。 但是现在我不能用下面的apt-get“覆盖”旧的包

我不想把所有在nginx中configuration好的网站搞乱，在这种情况下是否有安全的升级方法？ 我需要realip_module，upstream_module，rewrite_module，memcached_module，headers_module，fastcgi_module，但是我不知道PPA中的软件包“nginx”包含了软件包中的所有模块。
从http://www.webupd8.org/2011/02/fix-dpkg-error-trying-to-overwrite-x.htmlfind答案
解决这个问题（在大多数情况下，但可能不是全部）很简单：寻找导致错误的文件的path – 在我的第一个例子中，将是“/var/cache/apt/archives/smplayer_0.6.9+svn3595-1ppa1 〜maverick1_i386.deb“，运行以下命令：
sudo dpkg -i --force-overwrite /var/cache/apt/archives/smplayer_0.6.9+svn3595-1ppa1~maverick1_i386.deb如果“–force-overwrite”不起作用，你可以尝试使用“–force-all”。
在上面的命令中，将“/ var …”replace为导致计算机上出现错误的.deb的确切path。 如果你已经从版本库安装了.deb文件，它位于/ var / cache / apt / archives中，但是如果没有的话，它就是你下载的地方（不pipe怎样，错误应该显示它的确切path，不得不手动查找它）。
上述命令的作用是强制覆盖2个包中存在的文件并导致错误。 然后，为了确保所有的软件包都已经安装成功，运行以下命令：
sudo apt-get install -f
