Comment 1 for bug 1700127

Ah, after digging in to this, it was addressed in the upstream apparmor tree in http://bazaar.launchpad.net/~apparmor-dev/apparmor/master/revision/3446 (basically, stderr was not being captured correctly when attempting to check whether the sysctl() syscall was supported in the test environment). Interestingly, the patch had already been cherry-picked into QRT for the 14.04-backport of 16.04's apparmor (where ppc64el doesn't support the sysctl() syscall), but was not also applied when testing apparmor on 16.04.

In any event, I have now modified the QRT test-apparmor.py script to apply the r3446 patch on 16.04 as well, in QRT git commit https://git.launchpad.net/qa-regression-testing/commit/?id=2646ed6f4e2c8f9b38eb3210f93a7439c6e8e5f0

Thanks!
