[keyfile]
unmanaged-devices=interface-name:lo
I added:
keyfile]
unmanaged-devices=interface-name:lo
in to /etc/NetworkManager/conf.d/unmanaged.conf and now I will reboot
EDIT:
This solved the problem, if somehow it was a problem... It just annoyed me...
]]>there is "lo" device connected... Why? What is that device?
NM was/is supposed to ignore the loopback device by default.
You can https://wiki.archlinux.org/title/Networ … ic_devices but there's probably an explicit connection, look into /etc/NetworkManager/system-connections/
what specifically to pay attention to
The "Purpose of Loopback" section in the answer with a tick.
I'm interested in why it hasn't appeared in the network manager until now???
No idea about that. I've never used NetworkManager in Arch.

P&P is my home wifi network.... I can not disconnect "lo", because always reconnects...
EDIT:
Solution is to make /etc/NetworkManager/conf.d/unmanaged.conf
and put this in to:
keyfile]
unmanaged-devices=interface-name:lo
You can also read something about this on this location:
https://forum.endeavouros.com/t/cabled- … ated/37221
Looks like it has to do with the update of the network manager and that is not a bug...
