I have tried all the above but did not work for me? I was running Ubuntu
16.04.2 LTS Xenial with no problem until two days ago. Then, after I did
a routine software update which I was prompted to do but Ubuntu software
updater, I had an error saying something went wrong. After I rebooted
the machine, I had no longer ethernet.
My card is realtek.
The command below
sudo lshw -C network
gave me -network UNCLAIMED
and doing ifconfig i do not see any ethernet connection there.
For now, I was able to get on the web and post this message to you only
because I had a backup exact copy of my 120gb SSD, hence I was able to
just change the SSD and get back to the Ubuntu system I had BEFORE the
update. I think this is a serious bug in Ubuntu, if did not have backup,
would have caused a lot of inconvenience, with me being unable to go on
the web using my Desktop PC.

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:
Won't Fix
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.
