Please bottom post.

Editing "/etc/resolv.conf" isn't going to persist if it's a symlink to
a file under "/run".

What's the output of

ls -l /etc/resolv.conf
ls -l /etc/netplan/*.yaml
cat /etc/netplan/*.yaml

To change the namerserver(s),

For a dynamic ip, use

network:
    version: 2
    renderer: networkd|NetworkManager #### choose one
    ethernets:
        eth0:
            dhcp4: true
            nameservers:
                nameservers: [192.168.0.1, 192.168.0.53] #### use yours

For a static ip, use

network:
    version: 2
    renderer: networkd|NetworkManager #### choose one
    ethernets:
        eth0:
            addresses: [192.168.0.111/24] #### use yours
            gateway4: 192.168.0.1 #### use yours
            nameservers:
                nameservers: [192.168.0.1, 192.168.0.53] #### use yours
