Comment 0 for bug 1568435

After upgrading to 16.04 tor is not start as service anymore, I have checked this `/var/log/tor/log` and it says:

Apr 10 10:11:34.000 [notice] Signaled readiness to systemd
Apr 10 10:11:35.000 [warn] Could not launch managed proxy executable at '/usr/bin/obfs4proxy' ('Operation not permitted').

If I stop tor service and I start tor with my user everything works fine so it looks something related to apparmor.
