Nginx 未满足依赖关系，无法升级/删除

最近我在我的 Ubuntu 服务器上安装了 newrelic，之后我开始在日志中自动收到无法加载 newrelic 扩展的错误。

我尝试升级/删除 newrelic 但在两种情况下都出现错误：

ubuntu@ip:/etc/php$ sudo apt-get upgrade
Reading package lists... Done
Building dependency tree
Reading state information... Done
You might want to run 'apt-get -f install' to correct these.
The following packages have unmet dependencies:
 nginx : Depends: nginx-core (< 1.10.0-0ubuntu0.16.04.4.1~) but 1.10.3-0ubuntu0.16.04.1 is installed or
                  nginx-full (< 1.10.0-0ubuntu0.16.04.4.1~) but it is not installed or
                  nginx-light (< 1.10.0-0ubuntu0.16.04.4.1~) but it is not installed or
                  nginx-extras (< 1.10.0-0ubuntu0.16.04.4.1~) but it is not installed
E: Unmet dependencies. Try using -f.

我尝试运行sudo apt-get -f install但结果输出：

我确实找到了一篇文章建议删除 nginx 然后重新安装。这是一台具有持续流量的生产服务器，因此我想避免卸载 nginx 之后出现故障的风险。我更改了 nginx 的配置，但没有记录所有更改。有什么安全的方法可以解决这个问题吗？

答案1

经过研究和试验了很多东西后，我找不到任何解决方案，最后遵循了这个https://askubuntu.com/questions/243568/nginx-dependency-problem-trying-to-upgrade

我做了以下事情：

  1. 我备份了/etc/nginx
  2. 然后删除 nginx
  3. 重新安装 nginx
  4. 然后，当它被/etc/nginx备份文件夹替换时，它开始工作

我做这些事大概花了 15 到 20 分钟的时间。

答案2

可以通过将 force-overwrite 传递给底层 dpkg 进程来解决此问题。这是我使用的命令：

sudo apt -o Dpkg::Options::="--force-overwrite" upgrade nginx

答案3

  1. 先跑吧apt list --upgradable。

  2. 下一次运行sudo apt-get install <package-name>从列表顶部的包开始。

  3. 再次运行apt list --upgradable以检查所有软件包是否已安装。 如果没有，请重复步骤 1 和 2。
