Network-Manager

[Goran]

I'm booting a 18.04-Server image, which was installed via debootstrap. All fine.

Further I installed network-manager to use is at the command prompt.

My goal is to boot any server and connect via any ethernetcard I plug
a cable into.

When I invoke

nmcli device status

I get an

enp9s0 ethernet unmanaged ---

So I went to /etc/network due to disable the interfaces file. But there is none.

What else can I do?

Netplan is not installed. It is no dependency. So I guess it is not
needed by NM.

My problem is solved with

touch /etc/NetworkManager/conf.d/10-globally-managed-devices.conf

this triggers NM to behave as it should be

touch /etc/NetworkManager/conf.d/10-globally-managed-devices.conf

As a follow-up, for anyone curious, the real problem is in the
/usr/lib/NetworkManager/conf.d/10-globally-managed-devices.conf file
Touching the /etc copy just effectively nullifies it.

The idea behind the default configuration is the belief that by default,
NetworkManager is the preferred interface to manage Wifi Connections,
but leave wired lan alone to the classic config.

If you jump through the netplan hoops, it will change that for you if
you specify Network Manager as your network configuration of choice.

But I would have to go on an whole different rant about netplan :)

Thanks for the info. Bizarre choice. But that's the way that it is...

netplan's a good idea. It's just a question of learning its yaml
format. It would've been easier to use RH's ifcfg's familiar .ini
format (and variables) but that ship's sailed.

Doesn't the server edition default to systemd-networkd?
