I've had this issue constantly since upgrading to Ubuntu v17.04 (not a VM). It was unusably bad. Fortunately, disabling IPv6 has been a consistently successful workaround for me:
1 Add the following /etc/sysctl.conf: net.ipv6.conf.all.disable_ipv6 = 1 net.ipv6.conf.default.disable_ipv6 = 1 net.ipv6.conf.lo.disable_ipv6 = 1 2 Run `sudo sysctl -p` after rebooting, cycling Wi-Fi, or changing networks. I feel silly writing this because I'm certain there's a better fix but it looks like other folks have tried similar workarounds. https://askubuntu.com/questions/886107/google-chrome-error-21-neterr-network-changed https://askubuntu.com/questions/440649/how-to-disable-ipv6-in-ubuntu-14-04 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1586528 Title: Avahi-daemon withdraws address record To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/avahi/+bug/1586528/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
