Ubuntu 换阿里源

直接去阿里云官方ubuntu镜像站找到对应系统版本的apt源

https://developer.aliyun.com/mirror/ubuntu?spm=a2c6h.13651102.0.0.2c3d1b11UG9kX0

下面是Ubuntu22.04例子

cd /etc/apt/
sudo mv sources.list sources.list.bak
sudo vim sources.list

deb https://mirrors.aliyun.com/ubuntu/ jammy main restricted universe multiverse
deb-src https://mirrors.aliyun.com/ubuntu/ jammy main restricted universe multiverse

deb https://mirrors.aliyun.com/ubuntu/ jammy-security main restricted universe multiverse
deb-src https://mirrors.aliyun.com/ubuntu/ jammy-security main restricted universe multiverse

deb https://mirrors.aliyun.com/ubuntu/ jammy-updates main restricted universe multiverse
deb-src https://mirrors.aliyun.com/ubuntu/ jammy-updates main restricted universe multiverse

# deb https://mirrors.aliyun.com/ubuntu/ jammy-proposed main restricted universe multiverse
# deb-src https://mirrors.aliyun.com/ubuntu/ jammy-proposed main restricted universe multiverse

deb https://mirrors.aliyun.com/ubuntu/ jammy-backports main restricted universe multiverse
deb-src https://mirrors.aliyun.com/ubuntu/ jammy-backports main restricted universe multiverse

● 更新apt

sudo apt update
sudo apt upgrade  --这步要等，可选择
