Can't explain better, but I found root cause. So, full steps to reproduce:
1) sudo service NetworkManager stop 2) sudo wpa_supplicant -c /etc/wpa_supplicant/wired.conf -i eth1 -D wired 3) sudo dhclient eth1 4) see in output "ls: cannot access '/run/systemd/resolved.conf.d/isc-dhcp-v6-***.conf': No such file or directory" 5) check ifconfig that only IPv4 address was received Work-around: Disable IPv6 for Ethernet ** Summary changed: - gnome-control-center reports Ethernet Connection Failure while Connection success + dhclient can't obtain IPv6 addr -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1850159 Title: dhclient can't obtain IPv6 addr To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/1850159/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
