Yes, this is actually the expected behavior. If netplan is configured to use the systemd-networkd backend for a given network interface (i.e. as set up by a default server installation) the "graphical UI" (NetworkManager) will ignore that interface; otherwise there would be conflicts
As you mentioned this can be changed by adopting the netplan configuration in /etc/netplan/*.yaml, defining the NetworkManager renderer, after which the interface will be handled by NM and can be controlled through the "graphical UI" and other NetworkManager tools, like "nmcli". I don't think the user's configuration should be overwritten by installing a meta-package like "ubuntu-desktop". ** Changed in: nplan (Ubuntu) Status: New => Won't Fix ** Changed in: network-manager-applet (Ubuntu) Status: New => Invalid ** Changed in: network-manager (Ubuntu) Status: New => Won't Fix -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1735979 Title: installing ubuntu-desktop package on ubuntu-server breaks wlan-config in netplan To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/1735979/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
