ubuntu操作-更改apt-get软件源

1、保险起见,备份 Ubuntu12.04 源列表

# cp /etc/apt/sources.list /etc/apt/sources.list.backup

2、修改源列表文件

# vi /etc/apt/sources.list

3、把里面的列表替换成下面的列表 
【163源 http://mirrors.163.com/ 】

4、更新软件源

# apt-get update

我使用的是163源,出现如下提示即更新成功:

......Hit http://mirrors.163.com precise-security/main Translation-enHit http://mirrors.163.com precise-security/multiverse Translation-enHit http://mirrors.163.com precise-security/restricted Translation-enHit http://mirrors.163.com precise-security/universe Translation-enReading package lists... Done


在 sources.list 文件中,我们看到很多“main,restricted,universe,multiverse”的字眼,这里顺便说一下它们的区别:

  • main —— 完全的自由软件。
  • restricted —— 不完全的自由软件。
  • universe —— ubuntu官方不提供支持与补丁,全靠社区支持。
  • muitiverse —— 非自由软件,完全不提供支持和补丁。

以及 precise 的字眼,其实 precise 是 Ubuntu 12.04 的 Code name,更多 Code name 如下所示:

    • Ubuntu 4.10 (Warty Warthog)
    • Ubuntu 5.04 (Hoary Hedgehog)
    • Ubuntu 5.10 (Breezy Badger)
    • Ubuntu 6.06 LTS (Dapper Drake)
    • Ubuntu 6.10 (Edgy Eft)
    • Ubuntu 7.04 (Feisty Fawn)
    • Ubuntu 7.10 (Gutsy Gibbon)
    • Ubuntu 8.04 LTS (Hardy Heron)
    • Ubuntu 8.10 (Intrepid Ibex)
    • Ubuntu 9.04 (Jaunty Jackalope)
    • Ubuntu 9.10 (Karmic Koala)
    • Ubuntu 10.04 LTS (Lucid Lynx)
    • Ubuntu 10.10 (Maverick Meerkat)
    • Ubuntu 11.04 (Natty Narwhal)
    • Ubuntu 11.10 (Oneiric Ocelot)
    • Ubuntu 12.04 LTS (Precise Pangolin)
    • Ubuntu 12.10 (Quantal Quetzal)
    • Ubuntu 13.04 (Raring Ringtail)
    • Ubuntu 13.10 (Saucy Salamander)
    • Ubuntu 14.04 LTS (Trusty Tahr)
    • Ubuntu 14.10 (Utopic Unicorn)
    • Ubuntu 15.04 (Vivid Vervet)
    • Ubuntu 15.10 (Wily Werewolf)
    • Ubuntu 16.04 LTS (Xenial Xerus)

      那么,除了 apt-get update,我们平常还会看到 apt-get upgrade 以及 apt-get dist-upgrade,它们的区别是什么呢?查阅相关资料,有如下解释: 
      An update should always be performed before an upgrade or dist-upgrade. upgrade is used to install the newest versions of all packages currently installed on the system from the sources enumerated in /etc/apt/sources.list. Packages currently installed with new versions available are retrieved and upgraded. 
      也就是说: 
      update 是同步 /etc/apt/sources.list 和 /etc/apt/sources.list.d 中列出的源的索引,这样才能获取到最新的软件包。 
      upgrade 是升级已安装的所有软件包,升级之后的版本就是本地索引里的,因此,在执行 upgrade 之前一定要执行 update, 这样才能是最新的。 
      由于包与包之间存在各种依赖关系,upgrade只是简单的更新包,不管这些依赖,它不和添加包,或是删除包。而dist-upgrade可以根据依赖关系的变化,添加包,删除包。
