无法删除旧内核

Question

我运行了命令：

dpkg -l | grep linux-image-

并得到了这份清单

rc linux-image-3.13.0-51-generic 3.13.0-51.84
rc linux-image-3.13.0-52-generic 3.13.0-52.86 rc linux-image-3.13.0-53-generic 3.13.0-53.89
rc linux-image-3.13.0-54-generic 3.13.0-54.91
rc linux-image-3.13.0-55-generic 3.13.0-55.94 rc linux-image-3.13.0-57-generic 3.13.0-57.95 rc linux-image-3.13.0-58-generic 3.13.0-58.97
rc linux-image-3.13.0-59-generic 3.13.0-59.98
rc linux-image-3.13.0-61-generic 3.13.0-61.100
ii linux-image-3.13.0-62-generic 3.13.0-62.102
rc linux-image-extra-3.13.0-30-generic 3.13.0-30.55 rc linux-image-extra-3.13.0-46-generic 3.13.0-46.79
rc linux-image-extra-3.13.0-49-generic 3.13.0-49.83
rc linux-image-extra-3.13.0-51-generic 3.13.0-51.84
rc linux-image-extra-3.13.0-52-generic 3.13.0-52.86 rc linux-image-extra-3.13.0-53-generic 3.13.0-53.89
rc linux-image-extra-3.13.0-54-generic 3.13.0-54.91
rc linux-image-extra-3.13.0-55-generic 3.13.0-55.94
rc linux-image-extra-3.13.0-57-generic 3.13.0-57.95
rc linux-image-extra-3.13.0-58-generic 3.13.0-58.97
rc linux-image-extra-3.13.0-59-generic 3.13.0-59.98
rc linux-image-extra-3.13.0-61-generic 3.13.0-61.100
ii linux-image-extra-3.13.0-62-generic 3.13.0-62.102
ii linux-image-generic 3.13.0.62.69

所以我然后跑了：

sudo apt-get autoremove linux-image-3.13.0-51-generic 

得到了这个：

Reading package lists... Done Building dependency tree
Reading state information... Done Package 'linux-image-3.13.0-51-generic' is not installed, so not removed 0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

那么我的系统上是否有未使用的旧内核，我应该如何删除它们？

Answer 1

在生成的内核列表的前两列中，dpkg -l您将找到有关软件包的信息，如下所示：

1. 列（所需的操作）：

   u = Unknown
   i = Install
   h = Hold
   r = Remove
   p = Purge
   

2. 栏（包裹状态）：

   n = Not-installed
   c = Config-files
   H = Half-installed
   U = Unpacked
   F = Half-configured
   W = Triggers-awaiting
   t = Triggers-pending
   i = Installed
   

对于你的第一个例子

rc linux-image-3.13.0-51-generic 3.13.0-51.84

因此，它会告诉我们软件包已被删除 ( r) 但配置文件仍然存在 ( c)。只有那些标记的内核ii才实际安装在您的系统上。自动删除只会删除过时的内核，但会保留配置文件。

要删除它们，我们必须清除已安装的软件包 ( sudo apt-get purge <package>)，但保留它们并没有什么坏处，而且它们不需要太多的硬盘空间。

Answer 2

sudo apt-get autoremove linux-image-3.13.0-51-generic

过去我在以下方面取得了成功：

sudo apt-get purge linux-image-3.13.0-51-generic
