I have noticed that doing a "sudo service network-manager restart"
usually fixes things, but not always and not for everything. For
instance, on my laptop at the moment firefox can't find any webpages
("Server not found"), but Chrome is working fine; ntpd is complaining
twice a minute in the log that it can't find 0.ubuntu.pool.ntp.org etc,
even though "nslookup 0.ubuntu.pool.ntp.org" gives a valid address;
"ping google.com" says "Name or service not known", even though
"nslookup google.com" returns a valid address. "dig google.com" is
working.-- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/1631241 Title: Name resolution stops working after resume from suspend Status in network-manager package in Ubuntu: Confirmed Bug description: After upgrading to Yakkety, when my Ubuntu GNOME laptop resumes from suspend DNS resolution stops working. After resuming, systemd-resolved is running and libnss-resolve is installed, but /etc/resolv.conf contains 127.0.1.1 as the the only name server. The dnsmasq-base package is installed since it is pulled in by both network-manager and lxc1, and both NM and libvirt have spawned instances of dnsmasq: > 1155 pts/2 S+ 0:00 grep dnsmasq > 2724 ?
