I have no experience configuring network manager by text configs, used only GUI. When moving mouse over NM tray icon there are tooltip "Not connected", however I see one connection then clicking it - "Wired unmanaged". Internet working fine.
I make new ethernet connection with priority 10 but it not appear in NM applet menu.

See # /etc/netplan for current configuration. # To re-enable ifupdown on this system, you can run: # sudo apt install ifupdown leonid@DevSSD:~$ cat /etc/netplan/01-netcfg.yaml # This file describes the network interfaces available on your system # For more information, see netplan(5). network: version: 2 renderer: networkd ethernets: enp3s0: dhcp4: true dhcp6: true nameservers: addresses: [127.0.0.1,127.0.0.53] search: [JR]
Question is: how to connect by new created ethernet connection, or at least make "wired" connection managed?
