No, $ apt-get install ifupdown redo your network config with /etc/network/interfaces and $ apt-get autoremove --purge netplan.io
Does not work if you not purge netplan. If installed, netplan insist to generate volatile config for networkd (/run/systemd/network/10-netplan-your_interface.network) with ipv6 options applied by networkd. It is not a kernel or systemd bug, but another netplan bug. If you do not want to go back to ifupdown, it's time to learn networkd. For server use, netplan is totally useless and only add a layer of potential new problems. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1771222 Title: Using sysctl to permanently disable IPv6 doesn't have any effect To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1771222/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
