> The exact conditions for reproducing this bug on mixed IPv4/IPv6 networks are not known
Looking at the upstream commit description, isn't it just that a DHCPv6 lease expires and the server NAKs a request for the same IP again? Or is that not sufficient to trigger the problem. In any case, I appreciate there might be difficulty in testing the fix, but what's the actual criteria you propose to use to decide when the bug is to be marked verification-done-bionic? ** Also affects: network-manager (Ubuntu Bionic) Importance: Undecided Status: New ** Changed in: network-manager (Ubuntu Bionic) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1969901 Title: network-manager fails to renew ipv6 address To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/1969901/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
