建议将所有常用镜像源保存在/etc/apt目录下,并命名为类似source.list.aliyun的形式,需要使用时直接复制替换source.list文件即可。

2更换方法及镜像源

Ubuntu采用apt作为软件安装工具,其镜像源列表记录在/etc/apt/source.list文件中。

首先将source.list复制为source.list.bak备份,然后将source.list内容改为需要的镜像源列表即可。
修改完成后保存source.list文件,执行:

sudo apt-get update 

打开Ubuntu的终端输入:

maliao@ubuntu:~$ sudo gedit /etc/apt/sources.list [sudo] maliao 的密码: 输入密码回车即可 

将镜像地址更改为以下任意一个地址(下面提供了阿里,网易,清华,中科大镜像源地址),保存即可。

更换好源之后执行下方命令更新:
sudo apt-get upgrade
