Apparmor fails boot and command line start with same result as below

x@x-NICEPUTER:~$ systemctl --failed

  UNIT             LOAD   ACTIVE SUB    DESCRIPTION

● apparmor.service loaded failed failed LSB: AppArmor initialization



LOAD   = Reflects whether the unit definition was properly loaded.

ACTIVE = The high-level unit activation state, i.e. generalization of SUB.

SUB    = The low-level unit activation state, values depend on unit type.



1 loaded units listed. Pass --all to see loaded but inactive units, too.

To show all installed unit files use 'systemctl list-unit-files'.



x@x-NICEPUTER:~$ systemctl status apparmor.service

● apparmor.service - LSB: AppArmor initialization

   Loaded: loaded (/etc/init.d/apparmor; bad; vendor preset: enabled)

   Active: failed (Result: exit-code) since Tue 2016-05-03 21:52:29 MDT; 1h 15min ago

May 03 21:52:29 x-NICEPUTER systemd[1]: apparmor.service: Failed with result 'exit-code'.

Directories apparmor/hardware/ and file graphics.d do not exist inside /usr/share/
Thus #include /usr/share/apparmor/hardware/graphics.d at line 26 of /etc/apparmor.d/usr.bin.webbrowser-app returns null and causes the failure.

How can I properly fix this or at the least create a workaround that allows apparmor.service to intialize without a failure?

Seems to be a reported bug (#1554803)

It can be solved installing apparmor-easyprof-ubuntu or creating the folders by hand.

sudo apt-get install apparmor-easyprof-ubuntu

For me, I couldn't install any packages because both ifconfig and network-manager could not find/start my USB wifi dongle.

So @xtrchessreal's comment is what worked for me:

In the recovery mode shell, create the following directories:

mkdir -p /usr/share/apparmor/hardware/graphics.d

mkdir -p /usr/share/apparmor/hardware/audio.d

mkdir -p /usr/share/apparmor/hardware/video.d

And then reboot
