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.
