ubuntu 20.04修改数据源配置

Ubuntu安装完毕之后,默认的源是Ubuntu自己的,但毕竟Ubuntu服务器在国外,我们访问起来会比较慢,可以将软件源切换为国内源,比如:阿里源,清华源,中科大源等等。在这边以清华源为例,其它源也是一样的道理。

1 切换源之前先把配置文件备份一份:

sudo cp /etc/apt/sources.list /etc/apt/sources.list.bak

2 找到清华源官网:

清华源官网

一定要选择与自己版本相对应的源,比如当前使用Ubuntu20.04,最好使用此版本的源,否则有可能会有意料不到的问题,良许就吃过这方面的亏。

网络上也有很多教你换源的帖子,但都是直接给出内容,有可能源与自己的版本不一致,所以最好自己去官网复制。

3.将之前的源全部删除

echo ” > sources.list

4.编辑新源文件

nano sources.list

5.加入新的数据源(清华数据源)

# 默认注释了源码镜像以提高 apt update 速度,如有需要可自行取消注释
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal main restricted universe multiverse
# deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal main restricted universe multiverse
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-updates main restricted universe multiverse
# deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-updates main restricted universe multiverse
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-backports main restricted universe multiverse
# deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-backports main restricted universe multiverse
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-security main restricted universe multiverse
# deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-security main restricted universe multiverse

# 预发布软件源,不建议启用
# deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-proposed main restricted universe multiverse
# deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-proposed main restricted universe multiverse

6.使用新源替换掉原来的源(一定要加sudo):

sudo vi /etc/apt/sources.list

7.然后更新软件包缓存:

sudo apt update

这个命令,会访问源列表里的每个网址,并读取软件列表,然后保存在本地电脑。

8.通常我们会紧跟着再执行命令:

sudo apt-get upgrade

这个命令,会把本地已安装的软件,与刚下载的软件列表里对应软件进行对比,如果发现已安装的软件版本太低,就会提示你更新。

9.备用数据源【阿里】
