root@ubuntus:~# apt-get remove nginx-light Reading package lists... Done Building dependency tree Reading state information... Done Package nginx-light is not installed, so not removed You might want to run `apt-get -f install' to correct these: The following packages have unmet dependencies: nginx-full: Depends: nginx-common (= 1.0.5-1ppa2~lucid) but it is not going to be installed E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution). 如何解决？

你搞乱了你的软件包仓库，破坏了你的系统。 所以你必须按顺序发布来解决它：
apt-get update apt-get upgrade apt-get install nginx-common apt-get remove nginx-full
在每一步仔细阅读信息，并按照给出的指示。
编辑：我说的依然如此。 你真的搞砸了你的设置。 强制安装永远不是一个好主意。 您试图安装不适合您的系统的软件包，然后强制另一个版本号的安装。 而我不知道你强制安装/更新/删除的其他软件包。 （ 2 not fully installed or removed.是一件坏事。）所以我会尝试
apt-get remove nginx-common nginx-full apt-get purge nginx-common nginx-full apt-get -f install
下次在安装其他Ubuntu / Debian版本的软件包之前，请三思。
我只是“转载”了这个问题：
apt-get update和apt-get upgrade 修正：
/etc/apt/sources.list.d/...注释掉了这行） apt-get purge nginx nginx-full nginx-common – 现在成功了 apt-get update ， apt-get install nginx
