[lxc-users] re lxcbr0 doesn't exist after upgrade to 15.10

[Stéphane Graber]

Note that the fix only works after a reboot, so make sure you reboot
after updating Network Manager.

However your error looks more like a conflicting DNS or DHCP server
being installed on your machine and already binding the ports needed by
lxc-net.
