Luis, you should do the following: sudo apt-get purge dnsmasq
then reboot (that's not really need, but is better), and then sudo apt-get install dnsmasq and all be fine! This is the problem neither dnsmasq nor networkmanager! This is the problem of upgrade! -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1048430 Title: "dnsmasq not available on the bus" To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/1048430/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
