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] Source: /usr/share/doc/netplan/examples/static.yaml
Follow with:
sudo netplan generate sudo netplan apply Did you connect? Test:
ping -c3 8.8.8.8 ping -c3
