Ubuntu中的这种依赖升级安全吗？

Question

我想在运行Ubuntu12.04LTS的内部生产服务器上安装PHP5。当我尝试使用apt-get安装时，它列出了大量的依赖项，并建议运行apt-get -f install。当我运行它时，我会得到它：

Reading package lists... Done

The following extra packages will be installed:
  linux-headers-3.2.0-59 linux-headers-3.2.0-59-generic linux-headers-server linux-image-3.2.0-59-generic linux-image-server linux-server
Suggested packages:

The following NEW packages will be installed:

The following packages will be upgraded:
  linux-headers-server linux-image-server linux-server
3 upgraded, 3 newly installed, 0 to remove and 379 not upgraded.
3 not fully installed or removed.
Need to get 51.4 MB of archives.
After this operation, 218 MB of additional disk space will be used.

这是在生产机器上进行的安全升级吗？我知道apt-get dist-upgrade很重要，而且可以破坏一些东西。这是小升级还是专业？

谢谢

/boot分区已满，不允许我运行apt-get -f install。当尝试从ubuntugenius dpkg -l 'linux-*' | sed '/^ii/!d;/'"$(uname -r | sed "s/\(.*\)-\([^0-9]\+\)/\1/")"'/d;s/^[^ ]* [^ ]* \([^ ]*\).*/\1/;/[0-9]/!d' | xargs sudo apt-get -y purge运行此脚本时，我得到以下信息：

rgs sudo apt-get -y purge

You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
 linux-headers-server : Depends: linux-headers-3.2.0-59-generic but it is not going to be installed
 linux-server : Depends: linux-headers-server (= 3.2.0.37.44) but 3.2.0.59.70 is to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

我觉得我现在陷入了一个循环，一个完整的/boot不允许我运行修理，但我不能清除/boot不运行修理。

为了获得以下错误，我成功地清除了/boot中的一些空间：

Answer 1

apt-get -f install是一种修复手术。因此，您的系统目前有问题，这是要修复的。

我的猜测是，如果您现在还没有安装内核，那么您确实需要这样做，因为您的系统现在甚至都无法启动！

Answer 2

这只是一个可用的内核升级。您可以毫无问题地进行更新。一旦重新启动，它将加载新内核。如果确实发生了什么事情，您可以在引导加载程序中选择旧内核，然后卸载最新的内核。
