Netplan is very strict about spacing, indentation, etc. For example, this is acceptable:

ethernets: enp3s0:

But this is not:

ethernets: enp3s0:

You may gain some insights by consulting the example files; for instance:

cat /usr/share/doc/

I suggest that you amend your yaml file to:

network: version: 2 renderer: networkd ethernets: eno1: addresses: - 10.10.1.64/24 gateway4: 10.10.1.1 nameservers: addresses: [8.8.8.8, 8.8.4.4]

Follow with:

sudo netplan generate
sudo netplan apply
