I could test package before going to 'noble-proposed'. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2085314 Title: systemd-networkd segfault (question #819069) To manage notifications about this bug go to: https://bugs.launchpad.net/systemd/+bug/2085314/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
