- remove the apparmor package with your package manager.
Is AppArmor enabled by default?
AppArmor is installed and loaded by default. It uses profiles of an application to determine what files and permissions the application requires. Some packages will install their own profiles, and additional profiles can be found in the apparmor-profiles package.
How do I know if AppArmor is enabled?
AppArmor is activated in the kernel, but no policies are enforced. Detect the state of AppArmor by inspecting /sys/kernel/security/apparmor/profiles . If cat /sys/kernel/security/apparmor/profiles reports a list of profiles, AppArmor is running. If it is empty and returns nothing, AppArmor is stopped.
Is AppArmor necessary?

What can AppArmor do to protect a Linux system?
AppArmor is a useful Linux security module that can restrict the file-system paths used by an application. It works differently than Security-Enhanced Linux (SELinux) and cannot run on at the same time on the same system with SELinux, which comes installed on some Linux distributions.
Which is better AppArmor or SELinux?
SELinux controls access based on the labels of the files and processes while AppArmor controls access based on the paths of the program files. While AppArmor is easier in administration, the SELinux system is more secure.
What is AppArmor in Debian?
AppArmor is a Mandatory Access Control framework. When enabled, AppArmor confines programs according to a set of rules that specify what files a given program can access. This proactive approach helps protect the system against both known and unknown vulnerabilities.
