I had the same bug, but my work around was the following: Manually take down your listening interfaces. My interface was eth0 (yours might be wlan0, br0, or something else. ifconfig usually lists only listening interface). sudo ifconfig <interface name> down -- for me this would be written sudo ifconfig eth0 down.
I then could restart the networking service sudo /etc/init.d/networking restart Everything worked after I took the interface down manually. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/663352 Title: No way to stop/start networking without network management To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ifupdown/+bug/663352/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
