12.04 测试版升级到 12.04 稳定版

Question

今天有很多关于从 beta 升级到 12.04 稳定版的建议，但大多数人只是说它们是一样的；根据我的经验，它们似乎不一样：

这是从我 12.04 的“测试版”版本运行的。

$apt-get upgrade:
The following packages have been kept back:

 linux-generic linux-headers-generic linux-image-generic


$ uname -a
Linux ****** 3.2.0-23-generic #36-Ubuntu SMP Tue Apr 10 20:39:51 UTC 2012 x86_64  x86_64 x86_64 GNU/Linux

$ sudo apt-get dist-upgrade

The following packages will be upgraded:

我们确定是一样的吗？看起来好像 release 有一个新的内核版本（-24-），如果不升级就无法安装 beta

Answer 1

dist-upgrade不是您认为的升级。它处理apt-get upgrade没有的包的删除和添加。因此，如果您sudo apt-get dist-upgrade在 12.04 测试版安装上运行 a ，所有软件包都将更新为最终的 12.04 状态。这与在最终版本发布后运行更新没有什么不同。
