[Bug 1172148] Re: isc-dhcp-server didn't restart after upgrade

Can you confirm that the md5sum of /etc/apparmor.d/usr.sbin.dhcpd is
c4a3f842da64006353d11d907b8b1752?

If it's, then try:
 - sudo /etc/init.d/apparmor reload
 - start isc-dhcp-server

The bug you're describing above is exactly the same as was introduced in
4.2.4-1ubuntu10.2 and then fixed in 4.2.4-1ubuntu10.3 so the fact you're
still seeing it suggest that apparmor didn't reload the profile
properly.

If the above doesn't work, I'd suggest trying to reboot the machine to
be perfectly sure that apparmor did parse the new profile.
