ubuntu怎么选择最快的更新源? ubuntu更改最快的更新源的图文教程

给ubuntu选择最快的更新源

1、打开设置》》软件和更新，如下图

2、下载自：下拉菜单，选择其他站点

3、你可以选择最佳服务器，也可以指定你满意的服务器。选择之后要求输入密码

4、选择关闭，之后会重新自动执行更新命令（sudo apt-get update），更新完成

安装Ubuntu18.04后，使用国外源太慢了，修改为国内源会快很多。

修改阿里源为Ubuntu 18.04默认的源

备份/etc/apt/sources.list#备份cp /etc/apt/sources.list /etc/apt/sources.list.bak

在/etc/apt/sources.list文件前面添加如下条目

#添加阿里源deb http://mirrors.ali***yun.com/ubuntu/ bionic main restricted universe multiversedeb http://mirrors.ali***yun.com/ubuntu/ bionic-security main restricted universe multiversedeb http://mirrors.ali***yun.com/ubuntu/ bionic-updates main restricted universe multiversedeb http://mirrors.ali***yun.com/ubuntu/ bionic-proposed main restricted universe multiversedeb http://mirrors.ali***yun.com/ubuntu/ bionic-backports main restricted universe multiversedeb-src http://mirrors.ali***yun.com/ubuntu/ bionic main restricted universe multiversedeb-src http://mirrors.ali***yun.com/ubuntu/ bionic-security main restricted universe multiversedeb-src http://mirrors.ali***yun.com/ubuntu/ bionic-updates main restricted universe multiversedeb-src http://mirrors.ali***yun.com/ubuntu/ bionic-proposed main restricted universe multiversedeb-src http://mirrors.ali***yun.com/ubuntu/ bionic-backports main restricted universe multiverse

最后执行如下命令更新源

##更新sudo apt-get updatesudo apt-get upgrade

另外其他几个国内源如下：中科大源
