Malformed Address '10.10.21.08/24', must be X.X.X.X/NN or

  • 772

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

    The error code indicates that there is a "Malformed Address" in "10.10.21.08/24".

    Try leaving out the leading zero in the fourth octet (i.e. write '10.10.21.8/24').
