I upgraded to Ubuntu 18.04 and suddenly I don't have internet on command line, wired nor wireless, some domains seem not to resolve, though
ping 126.96.36.199 does work, but
service networking status is outputting error. I saw many tweaks here on askubuntu regarding the issue, with
/etc/network/interface but none fully works.
sudo service network-manager restart does not work either.
My network is basically a mess. Is there a way to fully reset network settings to a functional one? How is it possible that Ubuntu is releasing a main distro with such a bug, since this is a hot topic around?
