temporary failure resolving “xxx“问题解决ubuntu设置dns

出现temporary failure resolving "xxx"或temporary failure in name resolution就是ubuntu没设置dns

sudo gedit /etc/netplan/03-netcfg.yaml

此文件有可能是不存在的，新建一个，然后按照下面文字替换自己的ip和网关即可

network:
        version: 2
        renderer: networkd
        ethernets:
                enp1s0: #网卡名
                        dhcp4: no
                        addresses: [192.168.66.65/24] # ip:192.168.66.65
                        gateway4: 192.168.66.1 #网关
                        nameservers:
                                addresses: [114.114.114.114,8.8.8.8]  #固定的dns服务器
