I'm having trouble starting the connection editor. I start
nm-connection-editor from the GUI, so I tried entering some new connections at there and when i try to see them in default Ubuntu network manger i don't see there, like this:
As you can see there is one raspberry zero Ethernet device which don't shown at the default network manger and also at right top corner bar this connection don't shown its name but shown it is connected!!!.
Also if i save some connection type at that default application by reconnecting for example the USB device this saved connection removed and need to made new by every connection to USB!!!. Anyone know what it means? I'm running Ubuntu 18.04 and haven't found any solutions for this error so far.
