UPDATE, network-manager team applied this to the 1.10-trunk as well and it was included in: 1.10.8 (first tag)
See: https://gitlab.freedesktop.org/NetworkManager/NetworkManager/-/commit/7fbbe7ebee99785e38d39c37e515a64a28edef0f Unfortunately Ubuntu 18.04 includes a version that is slightly too old to include this change: 1.10.6-2ubuntu1.1 ** Description changed: We have experienced this issue on mixed ipv6/ipv4 corporate network on Ubuntu 18.04. Unfortunately next LTS release is not yet an option for us. This is same as https://bugzilla.gnome.org/show_bug.cgi?id=783391 + This was fixed in 1.12.0. Could you consider including the below patch on ubuntu 18.04? https://cgit.freedesktop.org/NetworkManager/NetworkManager/commit/?id=17009ed91da8b3e0b10ee7e94d220be9bd3fa84c The patch can be applied with some adjustements on top of the version of network manager included in Bionic (pull-lp-source network-manager bionic). A function name has changed, changing the function name in the downloaded patch is enough to apply the patch. cat ../57ab9fd60fc9ec3ab7bc3fcef40b1f003d614162..17009ed91da8b3e0b10ee7e94d220be9bd3fa84c.patch |sed 's|nm_dbus_object_clear_and_unexport|nm_exported_object_clear_and_unexport|g' > modified_patch.patch This has been tested on some devices and so far we have not seen any problems ipv4 only network (cable/wifi) ipv6/ipv4 mixed network (cable/wifi) -- 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
