Public bug reported:
Relatively recently, after I reboot Ubuntu 19.04, the wireless network
connects but DNS is not working. This is because the /etc/resolv.conf
file, which is a symlink to ../run/resolvconf/resolv.conf, has no
nameserver entries:
# 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.
Either turning the wireless card off and on again or running "sudo
systemctl restart systemd-resolved" fixes the problem.
This is also a problem after resuming from suspend - either the
resolv.conf file has no nameservers, or the previous nameservers are
still in it and appear before the new ones (so DNS queries time out).
