从终端更新系统

我想从终端更新我的 Ubuntu 14.04 系统，我知道这些sudo apt-get update && sudo apt-get upgrade命令，但当我检查更新管理器时，内核更新仍然存在。这是为什么？我该怎么做才能从终端更新内核。

答案1

您需要执行dist-upgrade才能安装/删除与使用 升级的软件包相关的所有依赖项upgrade。从apt-get 手册页：

  dist-upgrade
       dist-upgrade in addition to performing the function of
       upgrade, also intelligently handles changing dependencies
       with new versions of packages; apt-get has a "smart"
       conflict resolution system, and it will attempt to upgrade
       the most important packages at the expense of less
       important ones if necessary. The dist-upgrade command may
       therefore remove some packages. The /etc/apt/sources.list
       file contains a list of locations from which to retrieve
       desired package files. See also apt_preferences(5) for a
       mechanism for overriding the general settings for
       individual packages.

因此，更好的升级方式是：

sudo apt-get update
sudo apt-get upgrade
sudo apt-get dist-upgrade

但是，使用时要小心，dist-upgrade因为它也可能会删除软件包以满足依赖关系。

apt-get upgrade 不会安装新软件或删除软件，这是安装新内核时必须执行的操作...请参阅线程。

你可以做的事情（摘自此主题，请阅读全文以了解更多信息)：

使用能力：

sudo aptitude update
sudo aptitude safe-upgrade
sudo aptitude full-upgrade

你也可以sudo apt-get dist-upgrade使用sudo apt-get upgrade
