DNS servers resetting after restart

[empleat]

I Am on last Ubunutu/Desktop. Using this command on admin account:

sudo nano /etc/resolv.conf

I change DNS servers, then open resolv.conf again to double check. And DNS servers are saved! Then after restart, all saved settings from resolv.conf are deleted!!! Any ideas why? Thanks!

Why it works like this I don't have a clue, but recent versions of Ubuntu are designed to rewrite the /etc/resolv.conf file at every reboot.
Depending on how your system is set up there are different methods for accomplishing this.

Here is a discussion of various techniques to accomplish that.

The easiest seems to use the GUI tool to add the DNS servers.

Goog luck.

I assume you have a good reason to be directly editing /etc/resolv.conf instead of the normal way to change DNS settings on a current Ubuntu desktop.

Please post output from running this command in Terminal -

realpath /etc/resolv.conf

What does /etc/resolv.conf reset to? Next time you perform a reboot and it resets, please post the contents of the reset /etc/resolv.conf file.

What are you using for networking? e.g. NetworkManager, wicd, netplan, /etc/network/interfaces, ...?
