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)

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.
