如何从我（足够大）/ boot中释放空间？

2

我正在尝试将Plex Media Server安装到我的Ubuntu服务器（14.04.2 LTS）之后 指南 但是当我开始安装Docker时，我在运行命令时遇到了以下问题 sudo apt-get install linux-image-extra-$(uname -r)： 

$ sudo apt-get install linux-image-extra-$(uname -r)
Reading package lists... Done
Building dependency tree
Reading state information... Done
linux-image-extra-3.13.0-53-generic is already the newest version.
linux-image-extra-3.13.0-53-generic set to manually installed.
You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
 linux-image-extra-3.13.0-68-generic : Depends: linux-image-3.13.0-68-generic but it is not going to be installed
 linux-image-generic : Depends: linux-image-3.13.0-68-generic but it is not going to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

然后当我尝试运行命令时 apt-get -f install 我收到以下错误： 

$ sudo apt-get -f install

现在，通过阅读我知道的错误信息 /boot/ 车满了，看着 $ df -h 它确实看起来很饱满。但是什么是清空驱动器的最佳方法，或者我可以移动驱动器 /boot/ 更大的分区而不影响主驱动器上的所有文件？

** 更新 **

这是我的输出方式 df -h 好像： 

$ df -h

而这里是我的输出 dpkg -l 'linux-image*' | grep ^ii： 

$ dpkg -l 'linux-image*' | grep ^ii

请发布输出 df -h 和 dpkg -l 'linux-image*' | grep ^ii。第一个命令将为您提供一个表，显示每个已安装文件系统的可用空间和已用空间，而第二个命令将显示所有已安装内核的列表。

谢谢。我已经用命令的输出更新了原始帖子。

你的/ boot目录已满！找到并删除不再使用的旧内核并将其删除（apt-get purge linux-image-3.13.0-43-generic）。你为什么这么多？只要让一对夫妇重新开始并重新开始。这将使您的启动列表更短。

可能是因为 apt 为每个内核更新安装一个新包，但不会自动删除不需要的包。

尝试：apt-get purge linux-image-3.13.0-43-generic linux-image-extra-3.13.0-43-generic。其余的都做同样的事情。请记住至少保留一个（在您的计算机上运行的那个），否则您的计算机将无法启动。

@simontan我也试过那个命令，但后来我得到了这个： Reading package lists... Done Building dependency tree Reading state information...

按照askubuntu.com上的这个指南解决了我的问题：

→ 释放/ boot文件系统上的空间 （显然在需要的地方将相关值替换为我自己的值）

按照上面的指南后，我运行了命令 apt-get autoremove 这清理了我/ boot分区上的一大堆空间。

现在我可以运行命令了 apt-get -f install 再次。
