Ubuntu软件源的修改比较简单，一种方法是直接修改软件软列表：只需要把所需的软件源添加到或直接替换原来的系统源列表就可以，列表文件就是/etc/apt/sources.list 。
在终端执行以下命令：
#进入所在目录： cd /etc/apt/ #备份源列表： sudo cp sources.list sources.list.bak #编辑源列表： sudo gedit /etc/apt/sources.list
如果希望把某一个软件源添加到列表，则只需要一个命令就好，比如在Ubuntu上安装搜狗输入法的时候，可能需要更新Fcitx，需要通过下面的命令添加其软件源：
sudo add-apt-repository ppa:fcitx-team/nightly
最后面的就是Fcitx的官方源了。
下面是一些国内比较好的源，请按照第一种方法添加。从以下各服务器列表内容中选择一段替换文件中的所有内容，也可以加在后面或前面，甚至可以添加多个。请根据自己网络环境设置更新服务器，以达到最快的速度。
经过测试下面这些源都可用，之前又一次重装系统由于不是长期支持版本官方源不可用了，从网上找了三个源都不能用，每次都提示404错误，换了下面的源就没问题了。另外，挑其中一两个就好，都加进去更新也比较慢。
