Netplan has made 3 big problem on this system with Ubuntu 19.10

[Farhad Mohammadi Majd]

$ nmcli connection up id Wired\ connection\ 1

Error: Connection activation failed: No suitable device found for this
connection (device lo not available because device is strictly
unmanaged).

# networkctl --all

and 2 links listed are "unmanaged"

==========================

Doesn't anyone know what to do after removing the netplan.io packae?!

Fortunately I have Fedora 31 on the another partition so I can easily
manaage NetworkManager and send these messages without having to deal
with FUCKING netplan!!

YOU UBUNTU DEVELOPERS SHOULD SERIOUSLY THINK ABOUT YOUR APPROACH IN
*twiddling* EVERYTHING IN THE SYSTEM INCLUDING CHANGING THE OFFICIAL
ICONS AND THEME OF GNOME!
