This annoying bug affected all upgrades to Bionic and Cosmic Cuttlefish I did so far and also effects Cosmic Cuttlefish. systemd-resolv and dnsmasq consume each 100% CPU and internet access becomes extremely slow.
My latest workaround is to disable automatic overwriting to /etc/resolf.conf with sudo dpkg-reconfigure resolvconf, and to replaced the spurious nameserver 127.0.01 in /etc/resolv.conf with nameserver 8.8.8.8 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1670959 Title: systemd-resolved using 100% CPU To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/dnsmasq/+bug/1670959/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
