Public bug reported: Hello, i've recently created a new ubuntu vm machine starting from xubuntu 17.10.
after disabling systemd-resolve i configured my wired connection to use my dns server on 127.0.0.1 and 9.9.9.9 as backup however network-manager is rewriting /etc/resolv.conf with the right search path but with the wrong nameserver (127.0.1.1) . this is my /etc/NetworkManager/NetworkManager.conf ##### [main] plugins=ifupdown,keyfile [ifupdown] managed=false [device] wifi.scan-rand-mac-address=no ##### This is the config of the interface # nmcli device show eth0 GENERAL.DEVICE: eth0 GENERAL.TYPE: ethernet GENERAL.HWADDR: 08:00:27:88:A7:A4 GENERAL.MTU: 1500 GENERAL.STATE: 100 (connected) GENERAL.CONNECTION: Wired connection 1 GENERAL.CON-PATH: /org/freedesktop/NetworkManager/ActiveConnection/3 WIRED-PROPERTIES.CARRIER: on IP4.ADDRESS[1]: 10.0.2.15/24 IP4.GATEWAY: 10.0.2.2 IP4.DNS[1]: 127.0.0.1 IP4.DNS[2]: 9.9.9.9 IP6.ADDRESS[1]: fe80::144b:10aa:bc15:b43a/64 IP6.GATEWAY: -- This is my resolv.conf cat /etc/resolv.conf # Generated by NetworkManager search nl.europe.intranet europe.intranet nameserver 127.0.1.1 As workaround i have fixed /etc/resolv.conf and chattr +i it but i think network manager should honor my conf . that wired connection is set up as dhcp address only. Btw that dnsmasq running on 127.0.0.1 is my configured dnsmasq not the one network managers used to use a long time ago: ps auxwww| grep dnsm dnsmasq 1764 0.0 0.0 57420 2828 ?
