[Pkg-utopia-maintainers] Bug#909958: network-manager: USB Tethering Connection Always Immediately Started - Cannot Turn Off

[Hans Streibel]

Package: network-manager
Version: 1.6.2-3
Severity: normal

Dear Maintainer,

I connect my PC (Debian9, Stretch) to the Internet via my mobile phone,
attached to my PC via a USB cable. Thus I use Tethering on my mobile phone.
Attaching the mobile phone this way to my PC gives me a USB network connection.

I configured that USB connection via the NetworkManager and told it NOT to
start the connection automatically. Connection name: "USB Samsung Galaxy S8".
And yes, its MAC address is correct.

Reboot.

When I plug-in the mobile phone (tethering connection) then I
immediately get a connection to the Internet, therefore:
- error: It was not configured so.

This might be a matter for the "network-manager-gnome package", I am not sure:
- the NetworkManager icon on the desktop gives the impression that I am
  not connected to the Internet (but well, in fact, I am): error
- Selecting the NetworkManager menu item "Ethernet Connected" shows up the
  sub menu item item:
  - Connect
  So what? I am already connected! Error.
  Clicking that menu item does not do anything.

Another option in the menu mentioned above is "Ethernet Connected -> Wired Settings".
When I select this menu item then I get a new window "Network" where the first item is
"USB Ethernet". Its menu topics are:
- USB Samsung Galaxy S8
  Last used: 7 days ago.
  What?! I am using it right now. At least I intend to use it right now.
  Yes, its MAC address is correct.
  Error.
- Ethernet
  This is my local cable connected Ethernet.
  Why is it shown here? I see a menu item "PCI Ethernet Connected" in my
  Desktop Menu, where it is mentioned, too. In my impression that is where it
  belongs.
  Anyway, that entry does not disturb here. Hopefully.
  Error?
- Wired Connection 1
  Where does this menu item come from? Who set it up? I did'nt.
  So it must have been set up automatically. It uses the default feature
  "auto-connect" which explains the behaviour that I am connected immediately.
  Obviously this is what is actually used for my mobile connection.
  Who set it up, and why? I personally did not configured that connection.
  The connection "USB Samsung Galaxy S8" should be used instead.
  Error
  BTW:
  There is no file for this connection "Wired Connection 1" in
  /etc/NetworkManager/system-connections
