Last time I messed with network interfaces at the command line, NetworkManager left the room...
Do you have any network connectivity at all? If so, use Synaptic to re-install NetworkManager a la:
viewtopic.php?p=1359273#p1359273
Network connectivity is currently enabled by the /etc/network/interfaces file and the networking service.
I have tried multiple iterations of removing the contents from there and modifying the various netplan and network-manager configuration files.
I can never get Network Manager to "own" the interfaces.
I can't imagine why finding the appropriate configuration file to make NM the "owner" of these interfaces is so difficult.
I have spent a number of hours on duckduckgo before posting here.
I may the only person that has ever tried to move from one network manager to another - other than a fresh install.
I sure can't find any mention or documentation on how to do it.
I have reconfigured the NM package and removed and reinstalled it from the command line previously.
Just did it again via the gui and selected all three NM packages ( network-manager, network-manager-gnome and network-manager-pptp ) instead of just Network-Manager.
I'm going to try a reboot and see if NM takes over now.
Nope, no joy.
Installation of Network Manager doesn't assume control of the interfaces, so I still need the list of NM files to modify and and to remove the interfaces from management of the other method.
Quite frankly if I could get the applet working with the way the interfaces are setup in /etc/network/interfaces, I'd prefer that.
Much saner configuration, but there are a couple of times when it is really convenient to enable/disable interfaces in the gui. :/
