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
