Check AppArmor details

Check if the kernel module is loaded:

cat /sys/module/apparmor/parameters/enabled

Check kernel loaded AppArmor profiles:

sudo cat /sys/kernel/security/apparmor/profiles

Check AppArmor status:

sudo aa-status

Profiles and processes are in either enforce or complain mode, directly analogous to SELinux's enforcing and permissive modes.
You can use dmesg to debug problems
