How to add DNS resolver (1.1.1.1) in a Linode with Ubuntu 20
I know that /etc/resolv.conf is dynamically updated by Ubuntu now. What is the best way to add a new server without breaking Linode network configuration?
Thanks!

While I can’t speak from personal experience on this matter, I looked around to see if others have run into a similar issue. Fortunately, this has been discussed in detail on askubuntu.com, and users have successfully made permanent updates to /etc/resolve.conf.
The process would involve making edits to your /etc/systemd/resolved.conf file, and then updating the symlink with /etc/resolve.conf. The below link provides excellent context and guidance for achieving this:
