安装Ubuntu 18.0.4

 

安装后

1.设置静态ip 与dns     参考链接：https://www.cnblogs.com/youname/p/15704027.html、https://www.cnblogs.com/mouseleo/p/14976527.html    

sudo vi /etc/netplan/xx-network-manager-all.yaml     照此图

 

 

sudo vi /etc/systemd/resolved.conf     只改DNS这行

DNS=8.8.8.8 114.114.114.114 223.5.5.5

 

sudo systemctl restart systemd-resolved
sudo systemctl enable systemd-resolved

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

再次查看 /etc/resolv.conf   即可看到dns地址已更新

 

2.更换国内源站           参考链接 ：https://www.cnblogs.com/zhaipanger/p/12805955.html

 

 

重启后正常可设置快照或检查点，方便回滚
