Downgrade in Ubuntu

有时安装了一些高版本的软件，却又后悔，想回到低版本。其实这个降级过程是比较麻烦的，不过还好，总还是有办法的。
首先，查出安装过的版本号，以firefox为例：apt-cache show firefox，记住你要安装的某个低版本(version)
接着，咱们正式降级：sudo apt-get install firefox=<低版本号>
还以firefox为例，它会引用其它好几个package，所以这些引用到的package也要一并降级。
如我今天将 firefox 从 3.62be 降级到 3.6 ：sudo apt-get install firefox=3.5.7+nobinonly-0ubuntu0.9.10.1 firefox-3.5-branding=3.5.7+nobinonly-0ubuntu0.9.10.1 firefox-3.5=3.5.7+nobinonly-0ubuntu0.9.10.1

Thanks to the authors of firebug, i can use it (version 1.1 beta) again in Firefox 3.0.
With firebug, we can check and debug HTML, CSS, DOM, and especially JavaScript.
