I take it you're talking about this thread
https://trisquel.info/en/forum/you-might-be-using-google-name-server
As quidam commented there, it was a mistake that's been fixed.
To get rid of the google dns, edit these files as super user and remove the
line with 8888
/etc/resolvconf/resolv.conf.d/original
/etc/resolv.conf
That's probably all you need to do. If however you cannot connect to the
internet after that, you need to (put temporarily thoes back so your net
works) and then find some other name servers and put those in the files
instead.
