Likely nobody will be interested in minor bugs for versions released a
couple of years ago. At current moment it is better to try trixie weekly
builds. Upstream developers often prefer reports for applications built
from development branch or at least for the latest released version.
The results were confusing and highlighted some issues with the
creation of network profiles in general, at least from my point
of view.
I would separate bugs in network-manager-gnome GNOME GUI and in
NetworkManager itself. That is why state reported by nmcli is more
important than checkbox GUI state.
The debian-specific issue is that (for historic reasons) first user
created by installer is added to the netdev group, so it can create
system-wide connections (without root password asked by polkit).
Additional groups have been dropped from adduser.
nmcli general permissions
The short version is that if the behavior with "Connect
Automatically" and "Make available to other users" is down to NetworkManager,
Since you are going to use your laptop as a "server" then you have to
make connections available to all users to not depend on whether some
user has been logging in or who is current local user.
In addition you add ignore carrier setting for specific network devices
in NetworkManager.conf, however it should not matter in the case of
enabled autoconnect.
then I sympathize with the suggestions to migrate from it to systemd-
networkd. If someone could point me to a simple guide for that I'll look
into it.
I think, NetworkManager should be able to handle you case reliably (with
proper configuration).
Arch and Debian wiki, man pages and some search engine should be your
friends. Sorry, I have not noticed introductory articles for
systemd-networkd in my notes and browsing history. For specific
questions stackexchange and various forum threads were helpful.
