在Ubuntu 12.04 LTS中更新内核似乎不起作用

时间：2012-12-13 01:35:36

标签： linux-kernel virtualbox ubuntu-12.04 kernel-module uname

我正在尝试将我的内核从Ubuntu 12.04 LTS从3.4.0更新到可用的最新版本，但无论我做什么，uname -r都会继续返回3.4.0。我也试过多次重启我的系统，但没有用。

sudo update-grub的输出如下：

如果有人知道如何更新/升级到最新的内核，那就太好了。 [当我说更新时，我不完全确定这需要什么，但我正在尝试安装标头，图像，特别是，构建模块（因为我相信VirtualBox不会在我的系统上运行因为某种模块问题）]。

作为一个抬头，我做了很多谷歌搜索试图找到答案，所以我尝试解决这个问题的方式极为多样，但我对整个内核的想法（并更新它们）和什么的工作知识包含它们，相当有限。

如果有必要的话，我会非常乐意在终端中运行任何命令，如果你确实遇到了答案，请记住我是'newby'的内核，如此详细的解释和步骤，或者链接非常感谢。

作为最后一点，我正在运行由Jay Lee的脚本安装的32位ChrUbuntu（只是fyi，/ dev / sda3上的未知Linux发行版和/ dev / sda5是ChromeOS [我的chromebook的默认操作系统]），这可能与此问题有关，也可能没有，但我不是专家，所以任何见解都会很酷，但绝不是必要的。
