I recently did an apt update on my laptop running cosmic. DNS was very slow and I got the degraded to UDP message. Investigation showed that /etc/resolv.conf symlinked:
lrwxrwxrwx 1 root root 39 Oct 22 2017 /etc/resolv.conf -> ../run/systemd/resolve/stub-resolv.conf I fixed it by removing the prefixed '..': lrwxrwxrwx 1 root root 37 Dec 2 11:54 /etc/resolv.conf -> /run/systemd/resolve/stub-resolv.conf and all is now good. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1725840 Title: resolvconf not correctly configured after update from 17.04 to 17.10 To manage notifications about this bug go to: https://bugs.launchpad.net/cubic/+bug/1725840/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
