Netplan DNS Problem

I’ve always encountered a problem with Netplan when I configure nameservers via Netplan. My expectation always was that whatever I configure as my namservers in netplan would be applied to /etc/resolv.conf but that doesn’t happen.

Netplan uses systemd-resolvd but by default it always creates a symbolic link from /etc/resolv.conf to /run/systemd/resolve/stub-resolv.conf which uses 127.0.0.53

Most of the time this doesn’t result in my desired outcome which is that I want the nameservers defined in Netplan to be explicitly configured in /etc/resolv.conf.

So here’s the solution to this problem:

sudo unlink /etc/resolv.conf
sudo ln -sf /run/systemd/resolve/resolv.conf /etc/resolv.conf

and then restart the service:

sudo systemctl restart systemd-resolved.service 

And we’re done! Your nameservers will now be applied. You’re welcome.
