Comment 1 for bug 116627

For doing a stable release update, please follow the process here:
  https://wiki.ubuntu.com/StableReleaseUpdates

If you want to just test locally, you can rebuild under feisty using the following series of commands:

 cd /tmp
 apt-get source apparmor
 sudo apt-get build-dep apparmor
 sudo apt-get install build-essential fakeroot devscripts

 wget http://librarian.launchpad.net/7690794/apparmor_2.0.1%2B510.dfsg-0ubuntu6.dsc
 wget http://librarian.launchpad.net/7690793/apparmor_2.0.1%2B510.dfsg-0ubuntu6.diff.gz

 rm -rf apparmor-*/
 dpkg-source -x apparmor*ubuntu6.dsc
 cd apparmor-*
 debuild -uc -us

The resulting .debs will then be available in /tmp
