Ubuntu 16.04 Same issue happened to me after updates. Apparmor failure with code 123 prevents system from booting. These directories were created manually in recovery single mode: mkdir -p /usr/share/apparmor/hardware/graphics.d mkdir -p /usr/share/apparmor/hardware/audio.d mkdir -p /usr/share/apparmor/hardware/video.d
but it made no effect. After that: apt-get install apparmor-easyprof-ubuntu System booted up successfully. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1554803 Title: apparmor: missing stub hardware directories To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/apparmor/+bug/1554803/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
