![我是否安装了错误的通用内核?](https://linux22.com/image/901804/%E6%88%91%E6%98%AF%E5%90%A6%E5%AE%89%E8%A3%85%E4%BA%86%E9%94%99%E8%AF%AF%E7%9A%84%E9%80%9A%E7%94%A8%E5%86%85%E6%A0%B8%EF%BC%9F.png)
我在生产环境中使用 14.04.5 LTS。
我认为我在使用 Trusty 时可能安装了 Xenial 的内核。如果我这样做了,我很惊讶他们竟然允许我这样做。
系统似乎运行良好,自从我设置以来一直如此。问题是我在横向模式下看到了这些软件包更新,当我执行通常的 apt-get update && upgrade 时,我在升级步骤时看到了以下内容:
The following packages have been kept back:
linux-generic linux-generic-lts-xenial linux-headers-generic
linux-headers-generic-lts-xenial linux-image-generic
linux-image-generic-lts-xenial
当我登录时,landscape-sysinfo 显示以下内容:

当我使用以下命令检查内核时:
dpkg --list | grep linux-image
我看到的是:

ii linux-image-generic-lts-wily 4.2.0.42.34
ii linux-image-generic-lts-xenial 4.4.0.109.92
我想知道我是否应该安装 3.13.0.153.163 内核,以及这是否会摆脱有关 Xenial 的“保留”消息。
这安全吗?
编辑:
我找到了最初获得这些说明的地方: https://wiki.ubuntu.com/Kernel/LTSEnablementStack
他们声称在 14.04 版 LTS 中使用 Xenial 内核……令人困惑。我记得我就是这么做的。
这是正确的吗?
