Ubuntu 17.04 on a Dell E6530, fresh install with copying of some networkmanager setup in /etc/ from good old Ubuntu 16.04.01 LTS and using the same home partition.
My version of this bug is really miraculous. It was here for a week, today disappeared. For a week I had problems with ONE of the four locations where I connect to the net: - home-wifi (OK) - home-cable (OK) - work-cable (BAD) - work-wifi (OK). Problems only with 17.04, 16.04 working flawlessly. Problem was repeatable - nslookup working until I started firefox. Firefox showing Google home page ONCE, then all requests showing "unavailable", even reloading the home page. Also any later nslookup failing with "REFUSED". Two days ago I upgraded following to "zesty-proposed", but it did NOT help for yesterday. Maybe it needed time???? Upgraded the following packages: libnss-resolve (232-21ubuntu2) to 232-21ubuntu3 libpam-systemd (232-21ubuntu2) to 232-21ubuntu3 libsystemd0 (232-21ubuntu2) to 232-21ubuntu3 libsystemd0:i386 (232-21ubuntu2) to 232-21ubuntu3 libudev1 (232-21ubuntu2) to 232-21ubuntu3 systemd (232-21ubuntu2) to 232-21ubuntu3 systemd-sysv (232-21ubuntu2) to 232-21ubuntu3 udev (232-21ubuntu2) to 232-21ubuntu3 Maybe today (Sat) my work net services are less/more overloaded, so DNS query timing is different? I will see again on Mon. Anyway, strange - it seems that some timing or some combination of circumstances break the local DNS system.... -- 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/1654918 Title: No Internet access with default of Automatic (DHCP) Status in Linux: New Status in NetworkManager: New Status in network-manager package in Ubuntu: Confirmed Bug description: Fresh 17.04 install, wireless router connects without any issue but there is no internet connection/access.
