Temporary failure resolving 'mirrors.aliyun.com' error after set static ip in /etc/netplan/0...yaml

I have a vm in vmware player, after changing dhcp4:ture into

 dhcp4: no addresses: - 192.168.134.127/24 gateway4: 192.168.134.1 nameservers: addresses: [127.0.0.53,192.168.134.1, 8.8.8.8, 1.1.1.1]

in /etc/netplan/00-installer-config.yaml

the ip is set seccessfully, but it seems that the server can not visit the internet anymore.

I get Temporary failure resolving 'mirrors.aliyun.com' . Seems that I have trouble in DNS. How can it be fixed?

update the output of sudo netplan --debug apply:

Netplan is quite specific about spacing and indentation. As well, your yaml file omits the renderer. I suggest that you edit your file to:

network: version: 2 renderer: networkd ethernets: ens33: addresses: - 192.168.134.127/24 gateway4: 192.168.134.1 nameservers: addresses: [192.168.134.1, 8.8.8.8, 1.1.1.1]

Follow with:

sudo netplan generate
sudo netplan apply

Did you connect? Test:

ping -c3 8.8.8.8
ping -c3
