Bug Description

doing a regular upgrade using the update-manager popup on a 16.04 machine, the update process hangs:

Setting up apparmor (2.10.95-0ubuntu2.2) ...
update-rc.d: warning: start and stop actions are no longer supported; falling back to defaults
initctl: Unable to connect to Upstart: Failed to connect to socket /com/ubuntu/upstart: Connection refused
insserv: warning: script 'binfmt-support' missing LSB tags and overrides
insserv: Default-Start undefined, assuming empty start runlevel(s) for script `binfmt-support'
insserv: Default-Stop undefined, assuming empty stop runlevel(s) for script `binfmt-support'
initctl: Unable to connect to Upstart: Failed to connect to socket /com/ubuntu/upstart: Connection refused
insserv: warning: script 'screen-cleanup' missing LSB tags and overrides
insserv: Default-Start undefined, assuming empty start runlevel(s) for script `screen-cleanup'
insserv: Default-Stop undefined, assuming empty stop runlevel(s) for script `screen-cleanup'

it sits at the last line forever. this machine has no fancy os level hacks, no PPAs in use, was installed with 12.04 initially and has only seen LTS->LTS upgrades.

re-running "apt-get -f install" in a terminal i can not even ctrl-C out of the hanging apt process, i have to kill -9 the underlying dpkg to get a prompt back.

looking at /var/lib/dpkg/info/apparmor.postinst, i see:

for a test i commented out the above update-rc.d code, seemingly this is not the issue, now i have apparmor hanging the same way, just without the error messages on "apt-get -f install"

@johnny ... note that you replied to a duplicate ... if you can not update apparmor with an up-to-date kernel that has the fix for the issue, you most likely face a new and unrelated bug and should file it as such.
