Comment 1 for bug 1480607

python3-libapparmor does need to support multiple versions of python3. The reason the 2.10-0ubuntu1 package didn't get python 3.5 support is that it was built in the ubuntu-security-proposed ppa (https://launchpad.net/~ubuntu-security-proposed/+archive/ubuntu/ppa) and binary copied over to wily-proposed. The ubuntu-security-proposed ppa does not have the -proposed (or -update) pockets enabled because we build packages for supported releases in that ppa as well that go into the -security pockets of released versions. The version of python3-all-dev that includes the dependency on python3.5-dev has not moved out of wily-proposed, which is why the apparmor build did not pick it up.

The apparmor 2.10-0ubuntu2 package currently in the ubuntu-security-proposed ppa which address the regression that prevented the 2.10-0ubuntu1 from migrating from proposed is also missing python3.5 support for the same reason. However, not doing a binary pocket copy and instead letting it rebuild in wily-proposed should fix that.
