--- Comment #3 from Nate Graham <n...@kde.org> ---
Changing status to reflect the full sad story.
The SMB1 protocol is deprecated and Microsoft strongly urges people not to use
it. Windows 2016 server does not support it, and Windows 10 only supports it if
it's used within the first 15 days (!). It's clearly not going to work in the
future. [1]
Kubuntu 18.04 ships with Samba 4.7.6, which uses SMB2 by default.
Network discovery is provided by the SMB1 protocol. [2]
In SMB2 and later, network discovery has to be provided by a separate protocol,
WS-Discovery.
There doesn't seem to be any Linux support for WS-Discovery, either in the
Samba project or elsewhere[3]
---
The Ubuntu people were left with two bad options: stay with the insecure and
deprecated SMB1 protocol to preserve the network discovery feature for many
(but not all) SMB resources, or move to the secure and supported version of the
SMB protocol and lose network discovery for all SMB resources. They chose the
latter.
You can make the other choice for yourself by adding "client max version = NT"
to /etc/samba/smb.conf.
At the moment there is sadly nothing KDE can do about this situation. The
decision of what SMB version to support is made by distros, downstream of us.
Making network discovery use WS-Discovery so that it would work with the newer
SMB versions would have to be done upstream of us so that everyone benefits
from it.
