安装ubuntu2004 2404并配置网卡后，DNS默认值任然为127.0.0.53

# 查看dns
nslookup baidu.com
;; Got SERVFAIL reply from 127.0.0.53
Server:         127.0.0.53
Address:        127.0.0.53#53

# 查看DNS文件是链接到stub-resolv.conf
ls -al /etc/resolv.conf
/etc/resolv.conf -> ../run/systemd/resolve/stub-resolv.conf

# 查看/run/systemd/resolve/下有resolv.conf，是正确的，和网卡一致
ls /run/systemd/resolve/

# 更新为正确resolv.conf

sudo mv /etc/resolv.conf /etc/resolv.conf.bak
sudo ln -s /run/systemd/resolve/resolv.conf /etc/resolv.conf
