[Bug 1028526] Re: dhcpd failed to start with apparmor denied: capname="dac_override"

[Launchpad Bug Tracker]

This bug was fixed in the package isc-dhcp - 4.2.4-1ubuntu4

---------------
isc-dhcp (4.2.4-1ubuntu4) quantal; urgency=low

  * debian/isc-dhcp-server.isc-dhcp-server[6].upstart: chown /var/lib/dhcp
    and the lease files to 'root:root'. This is needed due to the change
    in 4.2.4-1ubuntu1 to use the upstream code for dropping privileges which
    requires the lease files be owned by root. (LP: #1028526)
