I opened nm-connection-editor and deleted the bridge.

Why did you delete it instead of fixing it and why didn't you add it again using the helpful tool instead of trying to do it the hard way?

I did try to fix it, but could not figureit out. So I decided to start over.

I also checked agaist backup and ther was no change in all
four of my /etc/NetworkManager/system-connections files

I did find that systemd-networkd.service had been disabled.
I re-enables and start it.  Did not help.


How to set up a bridge with nmcli:

Reference(s):
     https://wiki.archlinux.org/title/network_bridge


# nmcli connection add type bridge ifname br0 stp no
Connection 'bridge-br0' (a7722855-1aa1-4da8-8251-40f145f23681) successfully added.


# nmcli connection add type bridge-slave ifname eno1 master br0
Connection 'bridge-slave-eno1' (52d4e5fa-20c5-4ccf-84fb-8f4b53b17a7a) successfully added.

I copied those lines, only substituting my ethernet device and it didn't have any trouble.

Have you modified any of the NetworkManager config files or added any?

I did try starting over, did not work.


This command stopped me cold.  Do you know what it means?

# nmcli connection up bridge-br0
Error: Connection activation failed: Connection 'bridge-br0' is not available on device br0 because device is strictly unmanaged
