Good news ! This bug seems to have disappeared since I upgraded my two PC toward Kubuntu 17.04. No problem for several weeks, after two years of problems...
In fact, it seems that Kubuntu does not launch anymore dnsmasq. It does not appear in the results of the command: sudo /etc/init.d/network-manager status In my package manager, I see that the dnsmasq package is not installed, but the dnsmasq-base is. Thanks to anyone who solved that ! -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1434986 Title: Not working network connection after boot To manage notifications about this bug go to: https://bugs.launchpad.net/network-manager/+bug/1434986/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
