ubuntu更换APT软件镜像源_jammy镜像源

之前试过阿里的镜像源，但是因为有些问题不好用，现在用的是以下镜像源。

#打开编辑Apt镜像源配置文件
sudo vim sources.list
 
#将原来的配置注释掉，添加新的配置
deb https://mirrors.ustc.edu.cn/ubuntu/ focal main restricted universe multiverse
deb https://mirrors.ustc.edu.cn/ubuntu/ focal-updates main restricted universe multiverse
deb https://mirrors.ustc.edu.cn/ubuntu/ focal-backports main restricted universe multiverse
deb https://mirrors.ustc.edu.cn/ubuntu/ focal-security main restricted universe multiverse
 
#确认保存就好了

这边要注意以下自己的ubuntu版本适合什么镜像源

# 查看系统信息
lsb_release -a

如果codename是jammy，则需要使用jammy的镜像源，如下

deb http://mirrors.aliyun.com/ubuntu/ jammy main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ jammy main restricted universe multiverse
 
deb http://mirrors.aliyun.com/ubuntu/ jammy-security main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ jammy-security main restricted universe multiverse
 
deb http://mirrors.aliyun.com/ubuntu/ jammy-updates main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ jammy-updates main restricted universe multiverse
 
# deb http://mirrors.aliyun.com/ubuntu/ jammy-proposed main restricted universe multiverse
# deb-src http://mirrors.aliyun.com/ubuntu/ jammy-proposed main restricted universe multiverse
 
deb http://mirrors.aliyun.com/ubuntu/ jammy-backports main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ jammy-backports main restricted universe multiverse
