*** This bug is a duplicate of bug 1676547 ***
https://bugs.launchpad.net/bugs/1676547
I'm adding an observation here because the NetworkManager work-around
thread is here and not in #1676547.
Confirmed with additional information: Ubuntu 20.04 workstation ISO
(downloaded August 2020) exhibits the issue when run in the LiveCD
"Trial" mode. The Gnome "Settings" UI does not by default show the
"Wired" menu by default even if the underlying NIC is not servicing
DHCP. The network icon is also missing from the top status bar.
This behavior differs from Ubuntu 16.04 & 18.04 LiveCD ISO images.
In my test cases, copying /usr/lib/NetworkManager/conf.d/10-globally-
managed-devices.conf to /etc/NetworkManager/conf.d and then setting
"unmanaged-devices=all" followed by restarting NetworkManager causes the
menu to appear.
It is worth pointing out that once installed the menu appears as
expected once rebooted, so this issue is specific to the LiveCD instance
and not the installed instance.
I'm not going to try to guess why the developers decided to hide this
functionality in the LiveCD, but I for one am disappointed because I am
working in a mixed DHCP/VLAN network environment where static IP
addresses are the rule rather than the exception.

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.
