一、修改源配置

这里使用的时候又出现了联不通的情况，换成国内镜像在update

cp /etc/apt/source.list /etc/apt/source.list.bak

vim source.list

换源地址修改完（网上有，注意：根据Ubuntu版本不一样，部分内同也会不一样）

bash 复制代码

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

这里又遇到最后几个 update 还是连不上

根据网上资料

/etc/resolv.conf 文件加上

复制代码

	nameserver 8.8.8.8
	nameserver 114.114.114.114

然后 apt update 就可以了

1、/etc/resolv.conf 重启被重置

嗯...... Do not edit 好家伙

1. 修改 /etc/systemd/resolved.conf 文件

$Resolve$
DNS=8.8.8.8 114.114.114.114

2.重启域名解析服务

systemctl restart systemd-resolved

systemctl enable systemd-resolved

3.备份当前的/etc/resolve.conf，并重新设置/run/systemd/resolve/resolv.conf 到/etc/resolve.conf的软链接

mv /etc/resolv.conf /etc/resolv.conf.bak

ln -s /run/systemd/resolve/resolv.conf /etc/resolv.conf

4.查看验证

cat /etc/resolv.conf
