Got the same issue after the upgrade. In my case: moshe@moshe-desktop:~/New$ grep . /run/resolvconf/interface/* nameserver 127.0.0.53
moshe@moshe-desktop:~/New$ cat /etc/resolv.conf # Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8) # DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN # 127.0.0.53 is the systemd-resolved stub resolver. # run "systemd-resolve --status" to see details about the actual nameservers. nameserver 127.0.0.53 The difference from Zoltn's issue is that I don't have the lines: options edns0 search home During the upgrade which was done using Wi-Fi, the connection went down but it was after the download completed so the upgrade ended. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1816530 Title: DNS servers are not being set in the system correctly when you upgrade from 16.04 to 18.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/resolvconf/+bug/1816530/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
