Can you please attach your /etc/NetworkManager/NetworkManager.conf ? NM is not supposed to create /etc/resolv.conf any more, so I suppose something else is going on. Can you please reproduce the failed state and then do
cat /etc/resolv.conf and copy&paste the output, and run journalctl -u NetworkManager.service -u systemd-resolved.service -b > /tmp/nm.log and attach /tmp/nm.log? ** Changed in: network-manager (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/1647133 Title: Network-manager 1.4.2-2ubuntu4 brakes network connection (Zesty) Status in network-manager package in Ubuntu: Incomplete Bug description: Network-manager will make my network connection immediately lost after updating to the newest version 1.4.2-2ubuntu4. However, downgrading to the previous version 1.4.2-2ubuntu3 the network connection is back again and fine. If, with this version, I remove the file (link) /etc/resolv.conf the network is broken again. Rebooting solves this, as network-manager creates a new resolv.conf file. The newest version 1.4.2-2ubuntu4 also creates the very same kind of file, but no network. I have the latest (Gnome-shell DE) updates installed and of course all packages that network-manager depends on. But not the ones it only recommends or suggests. Should I have resolvconf installed? I think not, as isc-dhcp-client only suggests it.
