[xenial] autopkgtest regression

[Martin Pitt]

On Xenial, linux' autopkgtests now consistently fail (http://autopkgtest.ubuntu.com/packages/l/linux/xenial/i386/):

======================================================================
  FAIL: test_easyprof (__main__.ApparmorTest)
  Test aa-easyprof
  ----------------------------------------------------------------------
  Traceback (most recent call last):
    File "./test-apparmor.py", line 1190, in test_easyprof
      self.assertEquals(expected, rc, result + report)
  AssertionError: Got exit code 127, expected 0
  [Errno 2] No such file or directory

  ======================================================================
  FAIL: test_python (__main__.ApparmorBindings)
  Test python binding
  ----------------------------------------------------------------------
  Traceback (most recent call last):
    File "./test-apparmor.py", line 2403, in test_python
      self.assertEquals(expected, rc, result + report)
  AssertionError: Got exit code 1, expected 0
  Traceback (most recent call last):
    File "/tmp/testlibZ6TSPQ/test-script", line 20, in <module>
      import LibAppArmor
  ImportError: No module named LibAppArmor

This could just be a missing test dependency (easyprof/the lib), or maybe also related to the "switch to Python 3.5 by default" transition in xenial-proposed.

This bug is missing log files that will aid in diagnosing the problem. From a terminal window please run:

apport-collect 1510362

and then change the status of the bug to 'Confirmed'.

If, due to the nature of the issue you have encountered, you are unable to run this command, please add a comment stating that fact and change the bug status to 'Confirmed'.

This change has been made by an automated script, maintained by the Ubuntu Kernel Team.

I think this may just need a no change rebuild for apparmor so that python 3.5 bindings are built.

This was already done in wily; python3-libapparmor_2.10-0ubuntu6_amd64.deb does contain LibAppArmor/_LibAppArmor.cpython-35m-x86_64-linux-gnu.so .

[Jamie Strandboge (jdstrand)]

I'm unable to reproduce this. I can say that a lot of tests fail due to bug #1511439. If I use 'sudo aa-disable /etc/apparmor.d/usr.bin.webbrowser-app' I can work around this.

$ sudo ./test-apparmor.py
...
test_easyprof (__main__.ApparmorTest)
Test aa-easyprof ... ok
...
test_python (__main__.ApparmorBindings)
Test python binding ...
  python
  python3
ok
...

If I remove python3-libapparmor (which also remove apparmor-easyprof), I see the same issue:
...

======================================================================
FAIL: test_easyprof (__main__.ApparmorTest)
Test aa-easyprof
----------------------------------------------------------------------
Traceback (most recent call last):
  File "./test-apparmor.py", line 1190, in test_easyprof
    self.assertEquals(expected, rc, result + report)
AssertionError: Got exit code 127, expected 0
[Errno 2] No such file or directory

======================================================================
FAIL: test_python (__main__.ApparmorBindings)
Test python binding
----------------------------------------------------------------------
Traceback (most recent call last):
  File "./test-apparmor.py", line 2403, in test_python

  File "/tmp/testlib707vau/test-script", line 20, in <module>
    import LibAppArmor
ImportError: No module named 'LibAppArmor'

It seems the kernel's team scripts aren't pulling in 'apparmor-easyprof'.

$ sudo apt-get install apparmor-easyprof
...
$ sudo ./test-apparmor.py
...
test_easyprof (__main__.ApparmorTest)
Test aa-easyprof ... ok
...
test_python (__main__.ApparmorBindings)
Test python binding ...
  python
  python3
ok
...

This is due to series specific information encoded into the kernel testing infrastructure. I've updated the infrastructure for Xenial.
