我检查了 Apparmor 的状态，并得到了以下信息：
xubuntu@xubuntu:~$ sudo apparmor_status
apparmor module is loaded.
0 profiles are loaded.
0 profiles are in enforce mode.
0 profiles are in complain mode.
0 processes have profiles defined.
0 processes are in enforce mode.
0 processes are in complain mode.
0 processes are unconfined but have a profile defined.
因此，我下载了一个配置文件：
sudo apt-get install apparmor-profiles
然后我又检查了一下：
xubuntu@xubuntu:~$ sudo apparmor_status
apparmor module is loaded.
0 profiles are loaded.
0 profiles are in enforce mode.
0 profiles are in complain mode.
0 processes have profiles defined.
0 processes are in enforce mode.
0 processes are in complain mode.
0 processes are unconfined but have a profile defined.
然后我卸载了 Apparmor：
sudo apt-get remove apparmor
重新安装：
sudo apt-get install apparmor
再次检查：
xubuntu@xubuntu:~$ sudo apparmor_status
apparmor module is loaded.
0 profiles are loaded.
0 profiles are in enforce mode.
0 profiles are in complain mode.
0 processes have profiles defined.
0 processes are in enforce mode.
0 processes are in complain mode.
0 processes are unconfined but have a profile defined.
我重新加载：
sudo service apparmor reload
xubuntu@xubuntu:~$ sudo apparmor_status
apparmor module is loaded.
0 profiles are loaded.
0 profiles are in enforce mode.
0 profiles are in complain mode.
0 processes have profiles defined.
0 processes are in enforce mode.
0 processes are in complain mode.
0 processes are unconfined but have a profile defined.
这里发生了什么事？
谢谢。
