【首选】命令行

sudo sed -i 's@//.*archive.ubuntu.com@//mirrors.ustc.edu.cn@g' /etc/apt/sources.list

# 一般不建议替换 security 源
# 镜像站同步有延迟，可能会导致生产环境不能及时安装上最新的安全更新
sudo sed -i 's/security.ubuntu.com/mirrors.ustc.edu.cn/g' /etc/apt/sources.list

# 使用 HTTPS 避免运营商缓存劫持
sudo sed -i 's/http:/https:/g' /etc/apt/sources.list

【次选】手动修改文件

sudo nano /etc/apt/sources.list

修改为如下内容：

# deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ jammy main restricted universe multiverse
# deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ jammy-updates main restricted universe multiverse
# deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ jammy-backports main restricted universe multiverse
