Ubuntu 19.10 19.04 18.04 18.10等系统版本修改国内镜像源 国内更新源

Ubuntu安装好之后下载软件总是很慢,原因在于默认镜像源为国外服务器访问较慢,更改为国内镜像源后显著提高访问速度。

较好用的国内镜像源:阿里云,网易,中科大,东软等

这里以Ubuntu19.10,阿里云镜像源为例
不同版本的系统代号不同,只需要修改镜像源中的系统代号就可以兼容自己的ubuntu版本。
19.10系统代号:eoan

Ubuntu 19.10 19.04 18.04 18.10等系统版本修改国内镜像源 国内更新源_第1张图片

1.镜像源文件存放在/etc/apt/sources.list下,拷贝一份sources.list文件,以防万一。

sudo cp -v /etc/apt/sources.list /etc/apt/sources.list.backup

2.使用gedit编辑镜像源文件。

sudo  gedit /etc/apt/sources.list

3.替换文件,将以下内容拷贝到sources.list,将下面代码中的  eoan 改为自己版本的系统代号即可。

19.10

4.改好之后更新一下

sudo apt-get update
sudo apt-get upgrade

至此Ubuntu的软件下载速度会大大提高
