在全新安装的Ubuntu 14.04.1 LTS我注意到，自动删除建议删除linux-image-generic，但linux-generic根本没有安装。
这是一个错误还是内核映像的管理发生了变化？
答案1
初始全新安装后，是否有软件更新/升级？通常，当运行软件更新时，您会收到自动删除旧内核的建议。
为了更好地回答您的问题，请运行：
sudo update-grub
复制并粘贴结果到这里，它看起来应该像这样：
Generating grub.cfg
Found linux image: /boot/vmlinuz-3.13.0-45-generic
Found linux image: /boot/vmlinuz-3.13.0-44-generic
等等.....这将让我们准确地看到您已安装的所有内容。
答案2
在从 14.04.1 iso 进行全新安装时，应该已经安装了软件包 linux-generic 3.13.0.32.38。
你可以通过这个来观察安装了哪些相关的包（我的例子是不是从全新未升级的安装开始）：
