i have tried everything you said here, restarting the network manager.service and the nmcli networking off and on. Eevn tried using static ip with nmcli, nothing is working on my vms. I tried to erase mine and create new one hoping the problem would simply go away but of course it wasn’t going to be that easy… any suggestions?
No need to restart if you are using the nmtui command
but ensure that we need to activate the service once quit from the terminal
But how would you preform a “restart” like the old systemctl restart network or service network restart commands did?
Thank you
Thank you!
Stay connected : nmcli networking off && nmcli networking on
Thank you!!!
