Apparmor初始化失败，退出代码123

Apparmor无法启动，并且命令行启动的结果与以下相同

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

目录apparmor/hardware/和文件graphics.d在内部不存在。 /usr/share/ 因此，#include /usr/share/apparmor/hardware/graphics.d在第26行/etc/apparmor.d/usr.bin.webbrowser-app返回null并导致失败。

我如何正确地解决此问题，或者至少创建一种允许apparmor.service初始化而不会失败的解决方法？

似乎是一个已报告的错误（＃1554803）

可以解决apparmor-easyprof-ubuntu手动安装或创建文件夹的问题。

sudo apt-get install apparmor-easyprof-ubuntu

对于我来说，我无法安装，因为两者的任何包ifconfig和network-manager找不到/启动我的USB无线适配器。

所以@xtrchessreal的评论对我有用：

在恢复模式外壳程序中，创建以下目录：

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

接着 reboot

就我而言，当我使用卸载快照包时，出现了问题apt-get remove snapd。检查系统日志，似乎快照卸载程序删除了一些目录，但没有删除引用它们的apparmor配置文件。我用修剪了软件包，apt-get purge snapd然后重新启动了apparmor，没有错误。
