Ubuntu 20.04换国内源 清华源 阿里源
Ubuntu 20.04 是 Ubuntu 的第 8 个 LTS 版本,其重大更新和改进将在 2030 年前终止,计划于2020年 4 月 23 日发布。
国内有很多Ubuntu的镜像源,包括阿里的、网易的,还有很多教育网的源,比如:清华源、中科大源。
我们这里以清华源为例讲解如何修改Ubuntu 20.04
里面默认的源。
编辑/etc/apt/sources.list
文件, 在文件最前面添加以下条目(操作前请做好相应备份):
清华源
# 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
然后执行命令:
sudo apt-get update
sudo apt-get upgrade
- 1
- 2
