环境说明:
系统版本:ubuntu 18.04
以下方法适用于
ubuntu 18.0.4
(版本号为bionic
),若为ubuntu
其他版本,将源链接中的bionic
改为其他版本号即可:
step 1:获取ubuntu版本号
lsb_release -a
其中的 Codename
一项为版本号
step 2:备份原文件(可选)
sudo cp /etc/apt/sources.list /etc/apt/sources.list.bak
step 3:修改源文件
ubuntu 的下载源更新源等存放在 /etc/apt/sources.list 中
用nano
编辑 /etc/apt/sources.list:
sudo nano /etc/apt/sources.list
下面包含了阿里云源和清华大学源,在打开文件后,注释或者清空里面的内容,任选一个国内源复制进去:
# 阿里云源

ctrl + O保存,ctrl + X退出即可
step 4:更新软件列表和升级
在终端上执行以下命令更新软件列表,检测出可以更新的软件:
sudo apt-get update
在终端上执行以下命令进行软件更新:
sudo apt-get upgrade
换源之后,都是从国内镜像站获取软件包,所以此时更新时的速度会比换源之前快上很多。
