error: connection[0]: the routing rule selector 'uid' is not supported in NetworkManger until NM 1.34

[flybyray]

even when running on nmcli tool, version 1.40.16-18.el8_10 output from # nmcli -v

I need to remove/comment out this block:

https://github.com/linux-system-roles/network/blame/53be949a5bfa445bcd72c90b5314a52d85904861/module_utils/network_lsr/argument_validator.py#L2685-L2694

not sure why the Support is not correct detected.

The role was run directly on the host itself

What really matters are the versions of:

• the currently running NetworkManager version (journalctl -b0 -u NetworkManager | grep 'is starting').
• the installed libnm version

Can you run rpm -qa | grep NetworkManager and rpm -qR NetworkManager | grep libnm to check the version of NetworkManager-libnm?

Probably in the managed host, the old NM daemon is still running after the upgrading of the package.
What version of NetworkManager is currently running (journalctl -b -u NetworkManager | grep 'is starting')? Usually, when upgrading NetworkManager, you need to restart the daemon (systemctl daemon-reload && systemctl restart NetworkManager).

I have this issue even on a EL9 ( rockylinux) based fresh installed host. Removing this code block allows me to use this role without noticeable issues.

libnm’s API provides two core aspects. One is NMConnection and NMSetting types, which help handling NetworkManager’s connection profiles. The other is NMClient, which is a cache of the D-Bus objects from D-Bus API. The code fails because the attribute is not directly part of the top-level NM module. Instead, it belongs to a related class, "NM.IPRoutingRule". The correct way to check the attribute is by using the following approach:

            for routing_rule in connection["ip"]["routing_rule"]:
                if routing_rule["uid"] is not None:
                    if not hasattr(
                        Util.NM().IPRoutingRule, "set_uid_range"
                    ):
                        raise ValidationError.from_connection(
                            idx,
                            "the routing rule selector 'uid' is not supported in "
                            "NetworkManger until NM 1.34",
                        )

Let me create a PR to fix it.
