Since than I don't have a Lubuntu 18.04 system anymore, so I'm not able to run `apport-collect 1883865', and I'm unable to assist debugging this any further. You may reproduce the bug by installing Lubuntu 18.04 using the .iso I mentioned above.
Please note that regular Ubuntu 18.04 is not affected, I was able to install and run it without any issues. The Lubuntu desktop environment on a regular Ubuntu 18.04 is not affected either. What _is_ affected: dbus + AppArmor after installing Lubuntu 18.04 using the .iso I mentioned above. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to dbus in Ubuntu. https://bugs.launchpad.net/bugs/1883865 Title: Lubuntu 18.04 doesn't boot because dbus-deamon crashes because of AppArmor Status in dbus package in Ubuntu: Incomplete Bug description: I experienced this dbus-deamon-cannot-start-because-of-apparmor bug right at the first boot after installing (SHA1) `048b0b8925f1816b28e3527bfcd47d2842fa9f5e lubuntu-18.04-desktop- amd64.iso`. Please note that the installer has downloaded some packages files, the bug may not be in a package in the .iso. The bug made the first boot unsuccessful, it got stuck indefinitely at the boot logo. After some debugging in recovery mode root shell, I observed that dbus-daemon was a zombie process, restarted by systemd every few minutes, and crashing within a second after each restart. I was able to get this error message: $ journalctl -u dbus -b -f | grep 'Failed to start message bus' Failed to start message bus: Error getting AppArmor context of bus: Permission denied I observed that all systemctl commands were timing out after 60 seconds, and systemd (strace -p 1) was repeatedly and in vain issuing a ppoll(2) system call for reading the dbus socket, and not making any progress with its other duties.
