Ubuntu18.10更换apt源

Ubuntu18.10更换apt源

进入apt配置文件

# sudo cd /etc/apt/     

将原来的apt源文件保存

# sudo mv sources.list sources.list.back

查看自己的Ubuntu

# lsb_release -a

显示

Distributor ID:	Ubuntu
Description:	Ubuntu 18.10
Release:	18.10
Codename:	cosmic

编辑sources.list配置文件

# sudo vim sources.list

可使用的国内源比较多，这里选择使用清华apt源(速度比较快)

注意在添加时，一定要和自己的Ubuntu的Codename(cosmic)一致，否则会安装软件时会出现版本不一致问题，导致下载失败

清华源

# 默认注释了源码镜像以提高 apt update 速度(未认证)
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ cosmic main restricted universe multiverse
# deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ cosmic main restricted universe multiverse
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ cosmic-updates main restricted universe multiverse
# deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ cosmic-updates main restricted universe multiverse
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ cosmic-backports main restricted universe multiverse
# deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ cosmic-backports main restricted universe multiverse
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ cosmic-security main restricted universe multiverse
# deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ cosmic-security main restricted universe multiverse

# 预发布软件源(可有可无)
# deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ cosmic-proposed main restricted universe multiverse
# deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ cosmic-proposed main restricted universe multiverse

最后一步

# apt-get update
# apt-get upgrade

到此配置完成，确实感觉速度比较快！
