I can reproduce this on clean install of Kubuntu 10.04LTS, although it's within a VM (in kvm) so the interface is virtual. Network connectivity is there, everything works as expected except it can't be managed via NM.
I didn't need to reboot, but I restarted the service: sudo service network-manager restart ** Changed in: network-manager (Ubuntu) Status: New => Confirmed -- [kubuntu] NetworkManager default unmanaged https://bugs.launchpad.net/bugs/465591 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
