一、配置用于更新的源文件( /etc/apt/sources.list) 

ubuntu下用如下命令获取更新：

sudo apt-get update

而使用该命令要获得更新，依赖于相关的配置文件： ／etc/apt/sources.list

要获得该配置文件的详细说明：用命令 ： man sources.list

wzb@ubuntu:~$ whatis sources.list<br /> sources.list (5) - Package resource list for APT<br /> wzb@ubuntu:~$ man sources.list | cat<br /> SOURCES.LIST(5) APT SOURCES.LIST(5)</p> <p>NAME<br /> sources.list - Package resource list for APT<br /> DESCRIPTION<br /> The package resource list is used to locate archives of the package distribution system in use on the system. At this time, this manual page documents only the<br /> packaging system used by the Debian GNU/Linux system. This control file is /etc/apt/sources.list.<br /> The source list is designed to support any number of active sources and a variety of source media. The file lists one source per line, with the most preferred source<br /> listed first. The format of each line is: type uri args The first item, type determines the format for args. uri is a Universal Resource Identifier (URI), which is<br /> a superset of the more specific and well-known Universal Resource Locator, or URL. The rest of the line can be marked as a comment by using a #.<br /> SOURCES.LIST.D<br /> The /etc/apt/sources.list.d directory provides a way to add sources.list entries in separate files. The format is the same as for the regular sources.list file. File<br /> names need to end with .list and may only contain letters (a-z and A-Z), digits (0-9), underscore (_), hyphen (-) and period (.) characters. Otherwise they will be<br /> silently ignored.<br /> THE DEB AND DEB-SRC TYPES<br /> The deb type describes a typical two-level Debian archive, distribution/component. Typically, distribution is generally one of stable unstable or testing while<br /> component is one of main contrib non-free or non-us. The deb-src type describes a debian distribution's source code in the same form as the deb type. A deb-src line<br /> is required to fetch source indexes.<br /> The format for a sources.list entry using the deb and deb-src types is:<br /> deb uri distribution [component1] [component2] [...]<br /> The URI for the deb type must specify the base of the Debian distribution, from which APT will find the information it needs. distribution can specify an exact<br /> path, in which case the components must be omitted and distribution must end with a slash (/). This is useful for when the case only a particular sub-section of the<br /> archive denoted by the URI is of interest. If distribution does not specify an exact path, at least one component must be present.<br /> distribution may also contain a variable, $(ARCH) which expands to the Debian architecture (i386, m68k, powerpc, ...) used on the system. This permits<br /> architecture-independent sources.list files to be used. In general this is only of interest when specifying an exact path, APT will automatically generate a URI with<br /> the current architecture otherwise.<br /> Since only one distribution can be specified per line it may be necessary to have multiple lines for the same URI, if a subset of all available distributions or<br /> components at that location is desired. APT will sort the URI list after it has generated a complete set internally, and will collapse multiple references to the<br /> same Internet host, for instance, into a single connection, so that it does not inefficiently establish an FTP connection, close it, do something else, and then<br /> re-establish a connection to that same host. This feature is useful for accessing busy FTP sites with limits on the number of simultaneous anonymous users. APT also<br /> parallelizes connections to different hosts to more effectively deal with sites with low bandwidth.<br /> It is important to list sources in order of preference, with the most preferred source listed first. Typically this will result in sorting by speed from fastest to<br /> slowest (CD-ROM followed by hosts on a local network, followed by distant Internet hosts, for example).<br /> Some examples:<br /> deb http://http.us.debian.org/debian stable main contrib non-free<br /> deb http://http.us.debian.org/debian dists/stable-updates/</p> <p>URI SPECIFICATION<br /> The currently recognized URI types are cdrom, file, http, ftp, copy, ssh, rsh.<br /> file<br /> The file scheme allows an arbitrary directory in the file system to be considered an archive. This is useful for NFS mounts and local mirrors or archives.<br /> cdrom<br /> The cdrom scheme allows APT to use a local CDROM drive with media swapping. Use the apt-cdrom(8) program to create cdrom entries in the source list.<br /> http<br /> The http scheme specifies an HTTP server for the archive. If an environment variable http_proxy is set with the format http://server:port/, the proxy server<br /> specified in http_proxy will be used. Users of authenticated HTTP/1.1 proxies may use a string of the format http://user:pass@server:port/. Note that this is an<br /> insecure method of authentication.<br /> ftp<br /> The ftp scheme specifies an FTP server for the archive. APT's FTP behavior is highly configurable; for more information see the apt.conf(5) manual page. Please<br /> note that a ftp proxy can be specified by using the ftp_proxy environment variable. It is possible to specify a http proxy (http proxy servers often understand<br /> ftp urls) using this method and ONLY this method. ftp proxies using http specified in the configuration file will be ignored.<br /> copy<br /> The copy scheme is identical to the file scheme except that packages are copied into the cache directory instead of used directly at their location. This is<br /> useful for people using a zip disk to copy files around with APT.<br /> rsh, ssh<br /> The rsh/ssh method invokes rsh/ssh to connect to a remote host as a given user and access the files. It is a good idea to do prior arrangements with RSA keys or<br /> rhosts. Access to files on the remote uses standard find and dd commands to perform the file transfers from the remote.<br /> more recognizable URI types<br /> APT can be extended with more methods shipped in other optional packages which should follow the nameing scheme apt-transport-method. The APT team e.g. maintains<br /> also the apt-transport-https package which provides access methods for https-URIs with features similar to the http method, but other methods for using e.g.<br /> debtorrent are also available, see apt-transport-debtorrent(1).<br /> EXAMPLES<br /> Uses the archive stored locally (or NFS mounted) at /home/jason/debian for stable/main, stable/contrib, and stable/non-free.<br /> deb file:/home/jason/debian stable main contrib non-free<br /> As above, except this uses the unstable (development) distribution.<br /> deb file:/home/jason/debian unstable main contrib non-free<br /> Source line for the above<br /> deb-src file:/home/jason/debian unstable main contrib non-free<br /> Uses HTTP to access the archive at archive.debian.org, and uses only the hamm/main area.<br /> deb http://archive.debian.org/debian-archive hamm main<br /> Uses FTP to access the archive at ftp.debian.org, under the debian directory, and uses only the stable/contrib area.<br /> deb ftp://ftp.debian.org/debian stable contrib<br /> Uses FTP to access the archive at ftp.debian.org, under the debian directory, and uses only the unstable/contrib area. If this line appears as well as the one in the<br /> previous example in sources.list a single FTP session will be used for both resource lines.<br /> deb ftp://ftp.debian.org/debian unstable contrib<br /> Uses HTTP to access the archive at nonus.debian.org, under the debian-non-US directory.<br /> deb http://nonus.debian.org/debian-non-US stable/non-US main contrib non-free<br /> Uses HTTP to access the archive at nonus.debian.org, under the debian-non-US directory, and uses only files found under unstable/binary-i386 on i386 machines,<br /> unstable/binary-m68k on m68k, and so forth for other supported architectures. [Note this example only illustrates how to use the substitution variable; non-us is no<br /> longer structured like this]<br /> deb http://ftp.de.debian.org/debian-non-US unstable/binary-$(ARCH)/</p> <p>SEE ALSO<br /> apt-cache(8) apt.conf(5)<br /> BUGS<br /> APT bug page[1].

该配置文件的说明，可以发现，apt-get  update 的源不仅可以源于互联网，还可以是本机文件，甚至cdrom；

这文件源的顺序，一般是，cdrom 其次，是本地网络（包括本地文件），再次是外网，也就是互联网喽。感兴趣，可以深入的探究!

我是比较懒，直接google一下 ubuntu 10.04 sources.list in china 看了几个链接，基本上都是互联网上的源，就直接把它们综合一下，

追加到我的／etc/apt/sources.list文件下了。

二、用 sudo apt-get update 进行更新
