Apparmor 初始化失败，退出代码 123

Apparmor 启动失败，命令行启动失败，结果如下

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'.

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

我怎样才能正确地解决这个问题，或者至少创建一个允许apparmor.service初始化而不会失败的解决方法？

答案1

似乎是一个已报告的错误（#1554803）

可以apparmor-easyprof-ubuntu通过手动安装或创建文件夹来解决。

sudo apt-get install apparmor-easyprof-ubuntu

答案2

就我而言，问题出现在我使用 卸载 snapd 包时apt-get remove snapd。检查系统日志，似乎 snapd 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 修剪了包apt-get purge snapd并重新启动了 apparmor，没有出现错误。

答案3

对我来说，我无法安装任何软件包，因为ifconfig无法network-manager找到/启动我的 USB wifi 加密狗。

所以@xtrchessreal评论对我有用：

在恢复模式 shell 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

进而reboot

答案4

步骤 1：进入 ubuntu 的高级选项

第 2 步：从 Linux 4.4.0-22 通用启动（恢复模式）

步骤 3：然后从列表中单击（dpkg）

步骤 4：等待片刻，然后输入'sudo-install-（next vesion）16.04 of ubuntu然后等待几分钟

步骤 5：然后恢复并重新启动
