AppArmor is a security extension (similar to SELinux) that should provide extended security, which usually causes more problems than advantages.
AppArmor was first made available to Ubuntu in Ubuntu 7.04 in Universe. AppArmor is usually installed and loaded by default.
sudo /etc/init.d/apparmor stop
sudo /etc/init.d/apparmor start
Reloading AppArmor profiles:
sudo /etc/init.d/apparmor reload

sudo update-rc.d -f apparmor remove

After reboot i have noticed that apparmor is still running even after being removed from system start-up. So, to uninstalled it:
sudo apt-get remove apparmor
