我有一台笔记本电脑，同时安装了 32 位和 64 位 Ubuntu 14.04。我刚刚注意到这些操作系统上有不同的内核版本（请参阅下面的日志）：
- 32位内核：3.19.0-58
- 64位内核：4.2.0-35
我的问题是 - 这是预期/正常的吗？我从下面的日志中可以看到，32 位版本声称内核来自linux-generic-lts-vivid，而 64 位版本来自linux-generic-lts-wily（两者都不是-trusty，并且实际上比它晚 - 但都来自trusty-security？！）。
我真的不记得我是否安装了导致此状态的某些东西。有什么推荐的方法可以让它们都使用相同的内核版本？

答案1
你可以通过运行以下命令将内核 4.2 安装到任何 14.04.x 版本：
sudo apt-get install linux-generic-lts-wily
它与 32 位或 64 位版本无关。
