I am running an Ubuntu Server on my VMBox and need to set static IP. By following the steps described in https://www.techrepublic.com/article/how-to-configure-a-static-ip-address-in-ubuntu-server-18-04/, I created the configuration file 01-netcfg.yaml as follows.

network:
  version: 2
  renderer: networkd        
  ethernets:
    enp0s3:
      dhcp4: no
      addresses: [10.10.21.8/24]
      gateway4: 10.10.21.100
      nameservers:
        addresses: [8.8.8.8, 8.8.4.4]

Running sudo netplan apply --debugresults in:

debug

Which I'm not sure if the process is succesful or not since it mentions a merged config but gives no error at the end. However, I can not connect to Internet. sudo ping www.facebook.com returns "Temporary failure in name resolution". ping 64.233.169.104 results in "Destination Host Unreachable". sudo apt-get update fails as well.

sudo lshw -C network:

 cat /etc/netplan/*

After trying the answer. 

cat /etc/resolv.conf

ls -al /etc/resolv.conf

ls -al /etc/netplan

sudo netplan generate --debug

sudo netplan apply

No output.

I am trying to set a static IP for my ubuntu server by creating a yaml file on /etc/netplan/ as follows:

network:
    version: 2
    renderer: networkd        
    ethernets:
        enp0s3:
            dhcp4: no
            addresses: [10.10.21.08/24]
            gateway4: 10.10.21.100

But sudo netplan apply returns an error: 

Error in network definition /etc/netplan/01-netcfg.yaml line 6 column 23: Malformed Address '10.10.21.08/24',  must be X.X.X.X/NN or ... ".
ip netplan
