apport uses the dpkg database to determine if a package is official. In your description we can see that apt does not know where the package was installed from.
$ apt-cache policy systemd systemd: Installed: 234-2ubuntu12.1 Candidate: 234-2ubuntu12.1 Version table: *** 234-2ubuntu12.1 100 100 /var/lib/dpkg/status 234-2ubuntu12 500 500 http://us.archive.ubuntu.com/ubuntu bionic/main amd64 This is why apport would not file a bug and said that it was not an official package. ** Changed in: apport (Ubuntu) Status: Confirmed => Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1730736 Title: ubuntu-bug claims systemd is not an official package To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/apport/+bug/1730736/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
