Hi, I believe I have the same issue, however there's differences that you installed Ubuntu 16.10 using chroot, while I installed Ubuntu 16.10 using netboot(and then tasksel ubuntu-desktop), here are the investigation results:
## Possible Cause ## The problem seems to be lies on the new override config introduced in 16.10: ``` * debian/10-globally-managed-devices.conf: ship a default config to explicitly unmanage anything that is not wifi or wwan: we definitely want NM to manage wifi and mobile data; and probably don't want it to touch wired in many cases. ``` which is installed at /usr/lib/NetworkManager/conf.d/10-globally- managed-devices.conf , with the following content: ``` [keyfile] unmanaged-devices=*,except:type:wifi,except:type:wwan ``` that unmanages all network interfaces except wifi and wwan, thus bluetooth interface in your case and ethernet case in my case are all unmanaged by default. According to the future changelog by Martin Pitt: ``` * network-manager.postinst: Don't create /etc/NetworkManager/conf.d/10-globally-managed-devices.conf override on new installations. We don't want NM to manage non-wifi/wwan on servers/cloud instances, and for desktops live-build now installs a netplan policy snippet to let NM handle all devices. ``` This is designed to not let NM manage those interfaces except in a desktop edition(possibly because servers normally uses the ifupdown mechanism to manage networking), what I'm confused is: * Why there's the need to do so when ifupdown NM plugin already provides the ability to unmanages the network interfaces that have settings in /etc/network/interfaces? * Why the config still working after user installs *ubuntu-desktop, rendering those network-interfaces unmanaged even when it is clearly not for server/cloud usage? ## Workaround ## Remove /etc/NetworkManager/conf.d/10-globally-managed-devices.conf, it works(TM) -- 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/1638842 Title: network-manager does not manage ethernet and bluetooth interfaces when Ubuntu 16.10 is installed using chroot/netboot method Status in network-manager package in Ubuntu: Confirmed Bug description: Hello, I installed Ubuntu 16.10 using a chroot. I use network-manager to manage connections. My system is up-to-date (so I use network-manager 1.2.4-0ubuntu1). Wifi works perfectly but I cannot connect to wired networks and using my phone's Bluetooth connection. Corresponding devices are said to be unmanaged by network-manager. nmcli dev outputs: DEVICE TYPE STATE CONNECTION enp1s0 ethernet unmanaged -- wlp2s0 wifi disconnected -- 6C:9B:02:2C:EE:2C bt unmanaged -- hfp/org/bluez/hci0/dev_6C_9B_02_2C_EE_2C gsm unmanaged -- lo loopback unmanaged -- The following command has no effect: sudo nmcli dev set enp1s0 managed yes I can connect to a wired connection by doing: ifconfig enp1s0 up dhclient enp1s0 There is nothing in the file /etc/network/interfaces. Everything works perfectly if I downgrade network-manager to this version: network-manager_1.2.2-0ubuntu0.16.04.3_amd64.deb (http://packages.ubuntu.com/xenial-updates/amd64/network- manager/download). I had to install libreadline6 and downgrade nplan to meet dependencies. I don't know what to join to this bug report so please ask in case anything is needed.
