I've uploaded conntrack-tools 1:1.4.4+snapshot20161117-6ubuntu2 to bionic. This version of the package defaults to using 'Systemd on' for conntrackd config. I tested upgrades from xenial to bionic with the following in the bionic config /etc/conntrackd/conntrackd.conf:
1) 'Systemd on' # upgrade is successful 2) Systemd config not specified # upgrade is successful (defaults to 'Systemd on') 3) 'Systemd off' # upgrade fails as expected with timeout I'll submit the patch back to Debian as well. Note: The package in my ppa now has the new package version. ** Also affects: conntrack-tools (Ubuntu) Importance: Undecided Status: New ** Changed in: conntrack-tools (Ubuntu) Status: New => Triaged ** Changed in: conntrack-tools (Ubuntu) Importance: Undecided => High ** No longer affects: conntrack (Ubuntu) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1761994 Title: Shift of conntrackd to systemd notification causes upgrade issues from Xenial To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/conntrack-tools/+bug/1761994/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
